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.
- They can be spawned by bosses, including C.H.A.D., Monstro II, and the Champion version of Duke of Flies.
- Some suspect them to be mosquito-ladybug hybrids. They have proboscis like mosquitoes but are red and fat like ladybugs.
- Another theory is that they are mosquitoes 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.
