The Cake and the Letter

Dear Mario,
Please come to the castle, I have baked a cake for you.
Yours truly,
Peach

Mario put down the letter and got his hat. "I can't wait to see Peach."
"I know I'll have Luigi and Yoshi to join." Mario looked around the room. "I have to stop talking to myself."

Luigi walked in the room and said, "Lunch is ready. Oh, are you going somewhere?" He asked.
"Yeah, I'm going to Peach's castle. She made a cake for me." Mario replied.
"Well, I'll put the food in the refrigerator and you can go see Peach."
"Why don't you come along too?"
"Are you sure?"
"Yeah, I was going to ask you anyway."
"Ok, let me get ready and put the food in the fridge and let's go." Luigi left the room and put the food in the fridge and grabbed his hat and met Mario outside.
"I tried finding Yoshi, but I couldn't find him."
"I was only in the house for thirty seconds."
"There is a new warp pipe to Yoshi's house."
"Oh, we better hurry so we're not late." Just then Wario walked in front of the house.
"What's the hurry? You look like you just got burned by Bowser! Oh wait, you always look like that! Ha Hah Ha!" Wario said.
Mario and Luigi looked at each other and sighed at Wario's poor sense of humor.
"We're heading to Peach's castle. She made a cake for Mario." Luigi said.
"Let me tag along!"
"NO!" Mario said quickly.
"Fine, let me join... Or I'll break your arm!"
"Fine!" Mario and Luigi said in unison.
"Hah, you fight a overgrown lizard and you get scared by me? You are wimps." Mario was about to insult Wario when the clock struck ten.
"We're going to be late!" Luigi said, and they all ran towards the nearest tunnel to Peach's castle.
