I know Grimlock has fists that fit right back into his body, and I know that Snarl and Slag have fists that attach. What about Sludge and Swoop and are those fists interchangeable?

Swoop and Sludge are just like their orginal G1 counter-parts, meaning their fists are attached in exactly the same way as the original toys.

So, short answer, no, their hands are not interchangeable.

What about Snarl and Skludge, though? I know they both have fists that attach and dteach. Are they interchangeable?
