Yup, same here.
Except for turning Max into himself I just looked inside Stinky's.
As far as I can tell, you can only do it till you talk to girl Stinky, then he will not show up stuck in his box.
Kind of sucked I couldn't finish all puzzles due to this
Sam: "We're 98% certain General Skun-ka'pe is evil."
Stinky: "And the other 2%?"
Max: "That he's crazy and we have to shoot him! But that may be wishful thinking on our part."
(Any resemblance to KOTOR is purely coincidential, really!)
