🥒 Forbidden Caterpillar Button

Forbidden Caterpillar Button is exactly what it sounds like: a gloriously pointless incremental clicker about tapping a caterpillar until reality gives up. Every tap mints Crawls and makes the caterpillar squash with a satisfying little sound, while the big number on screen climbs and climbs. Spend your Crawls to summon Caterpillars — and this is where it gets silly. Each one you summon joins a bouncing physics horde that ricochets around the whole screen and auto-taps for you, so the more you buy, the more chaotic and crowded your screen becomes. Stack one-off upgrades like Stronger Taps, Mega Taps and Frenzy to multiply everything at once. Every time your total crosses a new power of ten, a CHAOS event fires: it rains caterpillars, the screen flashes and the count goes parabolic. Your progress and best score save automatically, and the horde keeps clicking even after you close the tab, so you collect a pile of offline Crawls when you return. It runs instantly in your browser on phone or desktop with touch and keyboard support — no download, no sign-up. Open Forbidden Caterpillar Button, start tapping, and let the absurdity snowball.
