A/N: So the impetus for this was a post I ran across on tumblr (and now can't find). Basically, Craig McCracken tweeted a thank you to Dan Povenmire for letting Mission Marvel be the lead in to the premier of Wander Over Yonder and Dan tweeted "We think everyone is gonna watch Mission Marvel just to make sure they don't miss the beginning of 'Wander Over Yonder.'" So I give you this fanfiction as a result of that. Enjoy guys!
"Oh my gosh. I'm so nervous." Wander stood backstage at Disney Channel Studios, his knees knocking together. "I'm not sure I can do this; maybe I should just walk away-"
"Hey Wander." He stopped, watching as a ten year old kid with bright red hair and a triangle shaped head walked up to him. "You ready to go on in about three weeks?"
"Three weeks?!" His legs shook harder. "It's that soon?"
"Hey, what's wrong?"
"I'm new here. I've never been to this studio before and...I was only born several months ago; I don't know how to do this. What if nobody likes me?"
The red head placed an arm around the creatures shoulders. "They'll like you Wander. You're a pretty adventurous guy. And hey, who doesn't like a phantasmagoric traveler?"
"But I'm following you! The Phineas Flynn!"
He raised an eyebrow. "What?"
The creature wriggled away from the boy, standing in front of him. "You're Phineas Flynn! People like your show! You build amazing things every week! Nobody can top that! And to follow you after Mission Marvel?" Wander sighed sadly. "I may as well give up right now."
Phineas laughed. "It's just a special episode where we work with super heroes and save the world. No big deal." The creature stared at him. "Really, it's not that big a deal. And the whole inventions thing?" The red head shrugged. "Ferb and I do that for fun. We only do it to beat the summer doldrums and prove the morning DJs wrong."
"Really?"
"Yeah! Sure, it's fun and we build lots of things and travel to different places, but Ferb and I haven't really done any phantasmagoric travel..." he trailed off and Wander sighed.
"Until now."
Phineas started, shaking his head. "Sorry. Habit." He placed a hand on the creature's shoulder. "Ferb and I won't do any phantasmagoric travel."
"Promise?"
"Promise." He paused in thought. "And hey, after a few weeks, nobody's going to remember Mission Marvel anyway. I bet your show will be way cooler."
"You really think so?"
"Yeah. I really do."
"Well..." Wander paused in thought. "I guess it won't be so hard following your show after all." He brightened considerably. "Thanks for the pep talk."
"Sure! Glad to help."
"Wander?" Craig walked over to him. "You're wanted on set. This is the last day of filming for season one. You ready?"
"Yep! Just let me find Sylvia."
The red head smiled as the creature bounded off in search of his steed. "He'll fit right in."
