Ewwww! These are some gross looking bugs and some of the biggest you'll ever come across. Don't panic, though. They are relatively harmless so avoid whatever they're launching and give 'em a good swat!

Typically found in clusters, blobs hop quickly around the room. The best bet is to hole up in the corner of the room and attack as fast as you can.

These guys scurry around the room like their smaller brood. They’ve got a mean tail swipe and will occasionally lunge at you with a burst of speed the moment they spot you.

These jellyfish aren’t much of a threat. They just drift lazily around the room. The orange ones are a bit tougher than the white but nothing to be concerned about.

These one-eyed amphibians hop around the room looking for their next snack. Stay alert! They can leap right over water and land on you when you least expect it. The red mutants are tougher and pack more punch than the green ones.

Owls stay airborne, so you’ll need to jump or strike from a higher platform to land a hit. They have an unfair advantage and can still hit you from their height though.

These sewer rats are reminiscent of the Rattus from StarTropics. They scurry around, pause for a quick spin, then dart off again. Defeat them before their tiny feet run all over you!

Direct from the big guy himself, these nasty mini-incarnations of the Prime Invader are stubborn and know nothing else except to kill Mike. Don't let them gang up on ya, or you could be in for big trouble. The green ones are tougher in every way.
