Ladybugs are the fourth enemy encountered in American McGee's Alice. They are found when Alice is in her small form. They basically appear to be mechanical ladybugs, which may be compliments of the Mad Hatter's constant experimentation on creatures of Wonderland. The Ladybug attacks Alice by dropping acorn-like bombs on her. Much like the Boojum, they hover around the player, making them a difficult target to hit, but in some instances they are very weak.
One particular ladybug is gigantic by size comparison and is strong enough to carry the marble used in an attempt to crush Alice. To avoid being crushed, Alice must run through a set of underground paths and halls in order to get to a safe point.
