http://www.morphsuits.com I can imagine Marco buying these, he's the one with the sense of humor. He'd be like "even if we have to demorph, they won't know who we are." and there'd definitely be a "Hey, they're called MORPHsuits" joke in there somewhere. They'd get that they were human, since Andalites can't wear them, but I can imagine him saying the group should make them their superhero suits lol. They even have an alien (Skrit Na like) one. I know Rachel wouldn't do it though. "I am not being caught in this thing. It's ridiculous." IDK about the other two humans, Jake and Cassie. Still, it made me laugh.
I should fanfic this, it'd be sooo funny.
