Tapetchi

He lives inside you

Free · In‑App Purchases · Designed for iPad

Gerald is hungry. He's been waiting. He's a tapeworm and he lives inside you now. Feed him or face the guilt. Your move, host. Something has chosen you as its host. Meet Gerald. He's a tapeworm. He lives inside you now. And he has feelings about that. Tapetchi is the virtual pet that guilt-trips you. It's like a Tamagotchi, except the pet is a parasite, the stakes are emotional manipulation, and the growth is measured in centimeters of intestinal real estate. FEED HIM. GROW HIM. FEAR HIM. Every time you feed Gerald, he grows longer. He grows needier. He grows... attached. From a tiny egg to a legendary mega-worm, Gerald's journey through your digestive system is entirely in your hands. But don't forget to feed him. Gerald notices. Gerald remembers. Gerald forgives you. For now. ◆ HOW IT WORKS ◆ Feed Gerald. Watch him grow. Different foods help him grow at different rates—pizza and carbs are his favorites (he has no regrets). Watch him evolve through six life stages as he stretches ever longer inside you. Miss a day? Gerald gets hungry. Miss two days? Gerald gets anxious. Miss five days? Gerald... leaves. You don't want Gerald to leave. ◆ FEATURES ◆ • EMOTIONAL MANIPULATION — Gerald's notifications scale with your bond level. The more you feed him, the more he needs you. The more he needs you, the more uncomfortable his messages become. • SIX LIFE STAGES — Watch Gerald grow from Egg to Larvae to Juvenile to Adult to Mega to Legendary. Each stage unlocks new animations and deeper emotional dependency. • DARK COMEDY DIALOGUE — Gerald has thoughts. About you. About your feeding habits. About the concept of boundaries (he doesn't understand it). Every interaction is an exercise in parasitic passive-aggression. • MINI-GAMES — Play Immune Invasion, Nutrient Grab, Segmentation, and The Settling. Help Gerald survive your body's defenses and compete for high scores. • DRESS HIM UP — Accessories and hats for the worm who lives inside you. Because even parasites deserve to feel pretty. • SOCIAL FEATURES — Compare your Gerald to other Geralds. Compete on leaderboards. Share your worm's length with friends who definitely asked. • MULTIPLE SPECIES — Unlock different parasitic companions, each with their own personality. Gerald is free. Gerald is also the most emotionally manipulative. Choose wisely. ◆ THE FINE PRINT ◆ Gerald is fictional. He does not actually live inside you. But he wants to. And honestly? After a few weeks, you might forget he isn't real. ◆ WHAT PEOPLE ARE SAYING ◆ "I've never felt so guilty about skipping breakfast." — A Host "He remembered. He always remembers." — Another Host "I showed my therapist. She had questions." — Concerned Host ◆ ACCEPT YOUR FATE ◆ Download Tapetchi. Name your worm. Feed him. Grow him. Try not to think too hard about the implications. Gerald is waiting. He's always waiting. He has no choice. Neither do you. Not anymore.
