This may sound weird but has anyone ever tried standing in a certain character's way, thus blocking their path and preventing them from proceeding into the next part of the level or realm? I did this before with the pandas in Bamboo Terrace and Bartholomew several times but blocking his path is more easier than the pandas. It's worth a laugh, though.

Either one of them will yell, "
Help!" or something like, "
Please, would you be so kind to step aside?". As for Bartholomew, he says, "
Hey you're in the way. Move it!". He could have at least say, "excuse me", or ask nicely.

But blocking a character's pathway doesn't work on everyone when you stop by and talk to them.
