A/N: I can't believe no one thought of this! A Blue's Clues and Doctor Who crossover! Steve and Joe's house is bigger on the inside. Miranda even said it in an episode. So yeah, this takes place after Meet Blue's Baby Brother and during the End of Time. Though, Sprinkles is only mentioned in this story.

A kid, about the age of 8, walked to the Blue's Clues house's front door. He had sandy brown hair and was slightly tan. He was Caucasian and had a backpack on as if he came back from school. He knocks on the front door.

A man in an orange shirt with squares on it answers. "Afternoon, Joe!" The kid smiles. "Hi Kevin!" Joe gleefully greets. "You'll never guess what." Kevin shows a puzzled look on his face. "My brother, Steve is coming back from college!" Joe smiles. "We're going to throw a surprise party for him! Will you help?" "Yeah!" Kevin yells. "You will?" Kevin looks back at his mom's car. She shakes her head.

"Sorry Joe. I have my sister's ballet recital to go to. I can't help."

"It's okay Kevin. We only needed help because Blue and Sprinkles are busy traveling the Sahara Desert in search of a mythical item."

"Really?"

"No, actually, they're in the Land of Great Discovery playing with Little Miss Muffet."

"Oh. Well, bye Joe!"

Kevin walks back to his mom's car. "Bye Kevin!"

Joe closes the door and heads for the kitchen. "Hey, Mr. Salt, what are we gonna do during the party?" Joe asks the salt shaker. "Well, we're going to have lots of party games like 'Pin the Tail on the Donkey.' Then, we'll tell Steve to tell us some of his adventures in college!" The French salt shaker responded.

"Sounds fun!" Joe gets excited. "I can't wait for this party!" The doorbell rings. "Who could that be?" Mr. Salt asks. "I don't know." Joe answers. He walks to the front door and opens it. It's Kevin. "Oh, hi Kevin! Didn't you have to go to your sister's ballet recital?" Joe asks. "I snuck out." Kevin answers.

"Oh. Then, can you help with the party?"

"Yes."

Kevin walks in. "Let's get Blue and Sprinkles first." Joe tells him. Joe moves the bookshelf out of the way to reveal a small door. They skidoo inside. They see Blue in front of a case. "Hey, Blue! Where's Sprinkles?" Joe asks. She points to the case. "Oh, he's in your room. Well, Kevin is gonna help us prepare for Steve's surprise party!" Blue cheerfully barks.

Kevin walks towards the mountains in the distance. "Kevin? Where are you going?" Joe asks. Kevin looks back with a mischievously angry look on his face. He grabs Joe with ease and runs to the mountain at superhuman speed. Blue chases after them.

She ends up in a cavern. She sees Joe chained to a wall. He is unconscious for the moment. Next to Joe is an extremely blue box. She has no idea why, but she makes a clue of it.

She hears footsteps and hides behind the box. It's Kevin and two alien type creatures. They are giant flies, except green skinned. Joe wakes up. "Kevin! Why are you doing this?" He asks. "I am not Kevin." "Kevin" announces. He removes a plate from his chest and transforms into a giant fly as well.

"The Doctor will surely take the bait now." The fly who was Kevin says in a British accent. "Who?" Joe asks. "None of your business. Just know that you are bait for a man called the Doctor."

"Well, who are you?"

"We are the Killer Flies of the planet Gargantuaflouratopia. I am the leader, Hans. To my left is Johann. To my right is Bobby."

"You'll never get away with whatever it is you're doing. Doctors are good people, and I'm sure that this Doctor is a good person. Plus, people will notice I am missing."

"That's what you think." Hans is about to put the plate on his chest to transform into Joe, but Blue snatches it and breaks it. "Get the dog!"
"Run Blue!" Joe yells. She runs away with the transforming plate in her mouth. Johann and Bobby scramble to catch her, but she is too fast. She makes a clue out of Hans, who overreacts and thinks it's poison.

"Use your wings, fools!" Hans yells as Blue jumps out of the cavern. They try, but their wings will not let them fly. The gravity on Earth is stronger than that of Gargantuaflouratopia.

She makes it to the rainbow slide, makes the plate a clue, grabs the chest and skidoos out of the Land of Great Discovery. She moves the bookshelf back in its place.

She gathers everyone to tell what happened, but they don't understand her. They all hear a knocking behind the bookshelf. Slippery Soap, and the rest of the characters in the house move the bookshelf out of the way. They are then grabbed by Johann and Bobby who have jet packs.

Mr. Salt, luckily jumps out of Bobby's clutches to save himself. He tries to save his family, but the flies fly away. After a moment of grief, Mr. Salt says, "Let's wait for Steve. He's the only one who can help us." He and Blue shut the bookshelf and wait for Steve.
