One Baby Spider

One Baby Spider is the opening phase of the Caves final boss encounter, a seemingly trivial enemy that serves as a fake-out before the real fight against Spinnerette begins. With only 10 HP, the One Baby Spider can be killed in a single hit by virtually any cat. However, experienced players know that this brief window before Spinnerette's arrival is actually the most important preparation phase of the entire encounter, and rushing to kill the baby spider without using the time wisely is a common mistake.

Defeating the One Baby Spider (or surviving the first round) immediately triggers Spinnerette's dramatic entrance from the ceiling with no transition screen or break between fights. This means any healing, buffing, item usage, or repositioning needs to happen before you deal the killing blow. Smart players will use this opening to heal their entire party, apply defensive buffs, position cats into an optimal formation for the Spinnerette fight, and use any consumables they have been saving.

The One Baby Spider itself poses minimal threat: it may web a cat, but the real danger is the Spider Kitten ally that spawns alongside it in the center of the arena. Do not waste all your abilities on this phase. Treat One Baby Spider as a free setup turn, not a real boss fight. Once you are fully healed, buffed, and positioned, deliver the killing blow and prepare for Spinnerette's 250 HP, web lobbing, Spiderling infestation, and ceiling retreat phases that make up the actual Caves boss encounter.
