I just noticed something about him in the game’s 2 boss fight! When he knocks you off and reaches the top of the tower, he takes a deep fiery breath and spits something out. I know this ain’t the vomit attack because ray says something along the lines of “sling it back at it”. Maybe this was a cut feature from the game or something, but I’d assume this is ray telling peter and the gang to throw the attack back at him. From the looks of it, seeing that nothing comes back at stay puft, reveals that they too were unsuccessful and probably died. I’m not lying! Replay the non remastered version, get killed by stay puft early during they fight, wait for him to get to the top, and watch him attack (and presumably kill) the ghostbusters! A bit dark of an Easter egg, NGL.
