Sucker will slowly float towards the player, dealing 1/2 heart of contact damage. It has similar health to Gapers and Moters, but upon death it triggers a 4-way blood bullet shot in cardinal directions. Each projectile is angled very slightly to its right.
Spit can be a much more dangerous enemy than the sucker. They fly towards the player at the same speed and have similar health, but fire an explosive green projectile on death (like Sloth), which takes 1 heart of damage and deals considerable area damage, outright killing any other monsters affected. They also tend to suicide if they are in close proximity to the player in order to deliver the projectile. However, they can be relatively easily exploited to blow up rocks or open secret rooms since they typically fire their projectiles at where the player was standing.
- Some suspect them to be mosquito-ladybug hybrids. They have probiscis like mosquitos but are red and fat like ladybugs.
- Other theory is that they are mosquitos full of blood just before the point of bursting, hence the color and fatness.
- It may also be a Tick-fly hybrid also at the point at bursting.
