Bombs are interchangeable between characters in freeplay. so if you spawn a bomb as batman and switch to penguin or vice versa you can still detonate them the same. no real practical use for this really.

In the yellow lift in the mission "Green Fingers", if you're playing Free Play mode, rapidly switching characters in the loading zone before you hit the top will cause you to be stuck at the top of the level. Killing your partner and switching to them will get you out but the elevator and zone won't work unless you restart the level.


in the first section of there she goes again, you might notice in the ocean there are some grates with minikits behind them. if you switch to a swimming character and punch these grates before you pull the switches to open them, you will break the sequence and you will not be able to get these minikits unless you restart the level. i've only tried this on the right one but it might work on both.

This is all i really know, but if you know anything feel free to type below in the comments!
