The Striklet has a rugged, frightening appearance. While it looks like a spider, it has only six legs and doesn't appear to be able to spin webs. A Striklet is entirely blue, has three pitch-black eyes, and has a stinger on it's rear end.
Little Oogie meets a Striklet who is eating, and Little Oogie tries to socialize, but the creature tries to attack him. Oogie then must defeat the Striklet in the combat tutorial. After, there is an optional mission, where you must defeat all Striklets in the area.
