| Brainsucker | A cross between a mosquito and a giant sponge. The only thing it loves more than brains...is salt! |
| Dankalanger | Hanging horrors that whip at anything within range. |
| Flibramax | Greasy electric eels with a little too much in the voltage department. |
| Freep | The freep is a bothersome creeping pest. To ruin your day it will try its best. If you choose to snooze near one, you'll get no rest. And NEVER jump into a freep family's nest. |
| Glactofan | This annoying monster silently scuttles across the floors of Castle Infinity's saltwater-soaked sectors. Fire off a flash cube or two and it will go away. |
| Grotchwally | When you're trying to hold on to your stuff, the last thing you want is this guy hanging over you! |
| Mentroscis | A highly intelligent jelly bag. Avoid its stifling stare, or else you'll find you can't jump. |
| Punchilicus | A sneaky monster that will try to trick you into getting close. Then, SCRAB-LA-BLAMM! It takes a whole lot of air freshener to stop one. |
| Ragmarauder | This is exactly why you shouldn't leave oily rags lying around. These monsters are a churning urn or burning funk. |
| Red Snyder | Annoying monsters that hang all over the Castle, waiting for things to pinch. |
| Rungus | He's big and he's bad. The very thought of you makes him mad. |
| Velocipesto | Two of the three things you hate worst in a predator: speed and teeth. Fortunately, the third thing is brains. That they don't have. |
| Vungus | This big, purple oozing sludge-sack just always seems to get in the way. Here's a hint, he'd be easier to get by if he were flat like a pancake. |
