Hijinx ensue, but they're not really all that wacky. Thing is, most of DW's transformations are apparently meant to be funny, but if so, they're jokes without punchlines: the writers seem to think that merely the fact of the transformation will be amusing. It's really not, though. I like how when transformed, his voice changes into a DW-voice imitation of the people he's being, but that's about it. It would've been more interesting, and made more sense, if the idea were that he changes into his conception of Launchpad, Gosalyn, etc. Then we could get some good character depth going. But as it stands: bah. There IS one sight gag I liked, where DW and Negaduck are falling off a cliff on DW's motorcycle thing and DW's all, relax! I'll just put this parachute on the cycle, and he does and, sure enough, the cycle slows its fall, only the two of them immediately fall off. Mebbe you had to see it.
Anyway, show, you gotta try harder than this.
