Hah yeah, Bloo would eat it up...
Luckily for Wilt, he's tall/fast enough to evade them for a while. I can imagine him running from them being similar to the scene from Love Potion #9 whenever the chick drinks the concentrated form and EVERYONE is chasing her down the street!

Eventually they'd corner him, though...
Wilt: "I'm really sorry but... AUGHHH!!" *girls tackle Wilt*
Random Girl: "EEEEEEEEE I GOT A SOCK!!!!!!!!!!!!!"
*Wilt manages to get up, but with comical kissy-prints all over his face*
And nightmares... aside from the obvious (his past), I'm trying to think of other things he might have them about. I know sometimes people dream about things that are really nightmares to just THEM, kinda like how I have
horrible dreams about being extremely late (I
HATE being late!)
Maybe he would dream about trying to help people, but only accidentally making things worse.
