My younger son was frightened of BOMSTERS.
There are three types of bomsters.
One type has big claws, and hisses and turns red when plunged into boiling water.
One type wears suits and carries machine guns and talks oddly.
One type lives under your bed and is likely to bite your feet off if you get out of bed in the middle of the night.
All bomsters, all scary.

Somehow the planes that drop things that explode, and the little furry critters that gnaw everything, escaped both the term and the fear.
