Note: Frozen is a film done by Disney. This story was something I originally made for Fanpop, then for a different fanfiction account, before I posted it here.

Princess Anna was excited about her birthday. It was early in the morning. She was wearing her pink pajamas and laying on her bed. She had been anticipating this day and was prepared to have the best birthday party ever. Her childhood birthdays were lonely and awkward, due to family drama. However, now that Anna had her sister back and had gotten herself a boyfriend, named Kristoff, Anna was expecting a much more cheerful and fun birthday. Anna woke up and said, "I wonder what Elsa and Kristoff have planned for me. Considering how much those two love ice, they'll probably get me some blocks of ice or something. Maybe they'll invite Ice Man, Mr. Freeze, and Captain Cold, in order to cool things off."

Anna rushed out of her room and ran to the living room. She and Elsa were sisters and close friends and Elsa was dedicated to throwing birthday parties for Anna, even when she had a cold. Because of all that, Anna was excited to see what her sister had planned for her. She was hoping for a cake made out of chocolate, chocolate-flavored sodas, and pinatas of Prince Hans and the Duke of Weselton.

Queen Elsa was wearing her green pajamas, as she walked to the living room and saw her sister running around. Elsa was often so busy with work, that she felt like she didn't have time for fun. She was thankful for her sister's energetic and fun-loving way of acting. She had an amused look on her face, while saying, "Well, you sure seem energetic, this morning."

Anna said, "Well, yeah. Today's a very special day. Very special."

Elsa shrugged her shoulders and said, "It's a pretty average day, but if you want to make each day feel special, that's something to admire."

Anna said, "You probably have a big surprise planned for me, because you're such a good sister."

Elsa had a confused look on her face, while asking, "Um, what are you talking about?"

Anna said, "Something's wrong." Anna went back to her room and said, "It seems like Elsa doesn't remember her own sister's birthday." She was disappointed about that, but she was determined to have a fun birthday party with her sister. She said, "I know how to remind her." Anna opened her dresser and started digging around the unorganized piles of clothes.

Elsa was finishing eating her breakfast, when Anna returned to the living room, dressed like a cake. Elsa was naturally confused, so she raised an eyebrow and asked, "Why are you wearing a cake costume?"

Anna said, "I'm pretty sure you know why."

Elsa asked, "Why do you even own that?"

Anna said, "Come on, Elsa."

Elsa was confused by her sister's behavior, but she tried to remain polite about it. She patted her on the back and said, "I hope that you work out whatever you're dealing with. I'm going to go take a shower." She started walking to her bedroom, while still feeling weirded-out by her sister's eccentric behavior.

Anna was disappointed. She went back to her bedroom and got on a purple dress. She paced around, while asking, "Could Elsa have really forgotten my birthday? That doesn't seem like something she'd do. However, she has been busy, thanks to all the kingdom-related nonsense she's pressured into doing. I can't blame her, for forgetting about my big day, even if I'm disappointed."

Anna got out her cellphone and gave Kristoff a call. Kristoff took a break from stacking blocks of ice, so he could answer his cellphone. He said, "Hi, Anna. What's going on?"

Anna replied, "Hi, Kristoff. I have a question."

Kristoff asked, "What is it?"

Anna asked, "Is today my birthday?"

Kristoff nervously started shaking, while saying, "Oh, no. Did I forget your birthday? If so, I'm in so much trouble."

Anna could tell how worried Kristoff was getting, while replying, "Don't worry, Kristoff. Calm down."

Kristoff responded, "I'm such a forgetful fool, for not remembering your birthday. Please, let me make up for it. What can I get you? A chocolate fountain? A diamond ring?"

Anna looked amused, while saying, "To be honest, both of those things are rather tempting. However, you shouldn't feel too guilty. Elsa also forgot about my birthday. Well, it's hard to tell if this really is my birthday, at this point. Could you hang on?"

Kristoff took a deep breath, before saying, "Sure."

Anna put the phone down and asked, "Is today really my birthday? I'll check, just to make sure." Anna checked the calendar and realized that it was Elsa's birthday, not hers. Anna facepalmed, while feeling ashamed of herself. She said, "Oh, no. I forgot my sister's birthday."

Anna picked up the phone and said, "Kristoff, I'm afraid I made a pretty dumb mistake. It appears this isn't my birthday, after all. That means you can stop feeling terrified."

Kristoff started having sighs of relief, before replying, "That's great to hear, Anna. I was worried I didn't know my girlfriend's birthday."

Anna responded, "You may know mine, but it appears you don't know Elsa's birthday."

Kristoff returned to being afraid, while saying, "Oh, no. I don't know my girlfriend's sister birthday."

Anna replied, "I also forgot about her birthday, so we can share the guilt. If anything, I should be feeling much more guilty, since I'm supposed to be the most knowledgeable, when it comes to Elsa."

Anna couldn't believe her mistake and she couldn't believe how modest Elsa was, by not telling Anna about her birthday. Anna felt like she wasn't being a good sister. She said, "Well, I'll change that. I'll give her a birthday party. Can you come to the kingdom, in a few minutes?"

Kristoff replied, "I'm sure Sven can give me a ride. However, I'm not sure what I'm supposed to get Elsa, for a birthday present."

Anna responded, "You can just give her some blocks of ice. You and Elsa are the two people I know, who love ice the most."

Kristoff replied, "Okay then. I'll get to the kingdom and help you with the party."

Anna smiled and said, "Thank you, Kristoff. You're the best."

Kristoff replied, "I love you, Anna."

Anna responded, "Love you, too."

Kristoff got off the phone and started putting blocks of ice on the sled, that Anna had given him. He walked up to Sven and said, "I'm gonna need you to pull this sled to Anna and Elsa's kingdom." Sven shook his head and yawned. Kristoff said, "Come on, old friend. It's Elsa's birthday. Anna forgot about it and so did I. I need to get there, not just because I don't want Elsa getting mad at me. I need to make sure Anna gives her sister the birthday party she deserves." Sven started taking the situation more seriously, when he realized the purpose of the trip. He nodded his head, to let Kristoff know he'd help him. Kristoff patted Sven's head and started heading to the kingdom.

While Elsa took a shower, Anna decorated the kingdom and got a vanilla cake ready. Anna said, "The party is ready. I can't wait. In fact, I won't wait. As soon as Elsa's overly-long shower is done, the party is going to start."

Anna heard a knock on the door. She sprinted to the door and opened it. She saw Kristoff and Sven, along with the blocks of ice. Anna hugged Kristoff and said, "Thank you for coming, Kristoff."

Kristoff asked, "Should I wrap the blocks of ice?"

Anna said, "Nah."

Sven nudged Kristoff. After putting a Band-Aid on his arm, Kristoff asked, "Can Sven come inside of the kingdom? He wants to celebrate Elsa's birthday."

Anna replied, "Well, the butler has been wanting a raise. He can earn that raise, by cleaning up Sven's footprints, after the party's over."

Kristoff responded, "Sounds good."

Kristoff and Sven walked into the house. Kristoff put the blocks of ice on the kitchen table. Sven opened the fridge and ate a bunch of carrots.

Elsa finished her shower. She was wearing a light-blue towel, as she stepped out of the bathroom. She was planning on going to her bedroom and getting dressed, but Anna delayed those plans of hers. Anna said, "Elsa, come on. I've got a surprise for you."

Elsa asked, "Can't you show me, later?"

Anna said, "No, I'm too excited."

Elsa pointed to the fact, that she was wearing a towel. She said, "But I need to get dressed."

Anna replied, "Your towel is modest enough, so let's go." Anna showed Elsa the birthday decorations. Anna said, "I forgot about your birthday, but I eventually remembered, so here you go."

Elsa admired her sister's effort and desire to give her fun times. She smiled and said, "Thank you, Anna."

Elsa looked around and saw Kristoff and Sven, who were waving at her, while wearing party hats, that were made out of ice. Elsa looked back at her sister and said, "Anna, you brought me into the kitchen, in a towel, while Kristoff and Sven are here? Are you trying to celebrate me or humiliate me?"

Anna replied, "Kristoff and Sven are like family, so it's cool."

Elsa said, "Also, how could you let a reindeer come inside of the kingdom?"

Anna replied, "The butler will take care of it."

Elsa sighed and responded, "Okay."

Anna replied, "Come on, Elsa. Let's go have some cake."

Elsa asked, "Now?"

Anna said, "Yep."

Elsa sighed and responded, "Okay." Elsa wasn't exactly fond of her current state of dress or the fact that a reindeer was roaming around the kingdom, but she was eager to have more fun with her sister. Anna and Elsa ate cake, together.

Kristoff asked, "How come this cake isn't made out of ice?"

Anna said, "Because that'd be weird."

Kristoff replied, "I've actually eaten cake, that was made out of ice."

Elsa raised an eyebrow and asked, "How did that taste?"

Kristoff said, "Pretty icy, but in a good way."

Elsa was embarrassed to still be wearing just a towel and she was upset about Sven eating all of the carrots, but she enjoyed the party that Anna prepared for her.

After they finished eating cake, Anna said, "I didn't have time to get you a present."

Elsa replied, "That's okay."

Kristoff pointed to the blocks of ice, while saying, "I got you these. Since you like ice so much, I figured you could add them to your ice collection. They're the same color as the dress you're wearing."

Elsa looked embarrassed, while replying, "I'm wearing a towel."

Anna said, "Don't worry. I have more stuff, for us to do. I got out all of your favorite board games. Let's play." Elsa agreed to play. The two sisters played games, for a few hours, while Kristoff admired the ice sculptures Elsa had made.

Anna said, "That was fun."

Elsa said, "Yes it was. Thank you."

Anna replied, "You're welcome."

Anna and Elsa hugged. Elsa walked back to her room and said, "I can finally get my dress on." Elsa looked at the sky and noticed it was dark. Elsa said, "Oh, never mind." She changed into her pajamas and started getting ready for sleep. Anna had given her a birthday party that was nicer and more fun, than she was expecting. She looked forward to her next birthday, but she hoped she wouldn't end up in a towel and have a reindeer making a mess in her kitchen, next time.
