Mutagen in Turtles Forever

[Coola Yagami]

I know the series had a few snags here and there when it came to the OT, like calling the Turtle Van the Party Wagon, and all the noogies as if it was an OT-trademark or whatever, but wow, the Mutagen thing was all over the place.

First off, that fly should have turned all-out humanoid (instead of just grow into a dog-sized insect) and talk and such.... sure it would have been too much like Baxter, but they could have some other insect or whatever... And why did the Mutagen turn the hyena guy and the Foot and such into mindless growling monsters... and yet TurtleHun was still able to talk and reason like Splinter/Bebop/Rocksteady do? I always figured Mutagen worked different once it entered 2K3Land, making them turn into just larger monsterous animals, rather than more humanoid, but Hun seems to be the exception of that rule.
