*swaps positions with his dude as he cannot drown* You can get me out later! I'll just wait here! (~.=.o)

Wait, why can't you drown/suffocate in sand?

*brings out a blackboard with info about his species* I'm related to Crocodiles which are pretty talented in that regard. They can hold their breath for around six hours continuously without the need to come up. Aside from that in my case there is that awesome stuff called Toonygen. In experiments the professors who helped me getting used to the modern society life around here, the stuff got used on me and enhanced that ability. I practically can hold my breath for superlong times making it seem like I can safe air in a way that I don't need to pick up new one in like ever. It definitely comes in handy to be a halftoon of a Totodile. Other great effects are that all sorts of toony mischief won't harm me, you see. X3

*Furiously jots down notes as if in a lecture, but consumes both the pencil and notebook accidentally as his concentration leaves what he's holding and focuses on your lesson*

Well, alright, just dunno about the teleportation/replacement bit :-P

Hehe, that's how toony physics work. In a way it's a bit like Substitute. I just need to grab into hammer space and wanna help my dudes or avoid impact with something and 'tadaa* there we go! People can do all sorts of silly stuff to me from inflating, melting, popping, flattening, changing and whatnot and after some while'pop' back and well. The worst I experience are seeing some stars and getting a lil dizzy. =D

is this somehow a reference to Aladdin?

It could be. It's not intended. I was just having a bit of fun with the idea that I was "Drowning in time" but that is no longer the case, lol

*Boop*
