Tokka & Rahzar are dumb because they're babies, not because of the mutagen, splinter was a smart rat from the start before he mutated it shows that and it's even said in the mirage comics and he raised the turtles so they followed in his foot steps.

He didn't seem very smart to start with and we only see Super Shredder on screen for what 3 or 4 minutes if that?
I'd hardly say that's enough time to establush if a character has some smarts or not.
