ROTSHARP, mirror-ape ogre

Sometimes when you're playing Super Mario Bros. 3, you may beat a level and then have to sit through several seconds of the roaming Hammer Brothers trying to make up their mind on where to settle next. Normally this process is only supposed to take a second--most of the time they only move one or two tiles each--but sometimes multiple Bros land on each other and they have to march around again. In tight spaces, this last ten seconds or longer! You may have wondered if it's possible for them to ever get stuck in an infinite loop and never settle down. The answer to that is yes! But it would be incredibly unlikely to happen by chance, since it does require some unorthodox play and some really lucky random number generation.

Make up your mind already!
