Dr. Beanies

Thomas A. Beanies is the first character the player encounters in Mewgenics, the doctor who brought you back to life with a defibrillator. After you complete the Caves and Boneyard chapters, Dr. Beanies appears on the map and begins accepting cats with Mutations, Birth Defects, Disorders, or Parasites in batches of five. Unlike other NPCs who provide direct stat upgrades, Dr. Beanies operates through a Side Quest system: every five donated cats earns you a random Side Quest Invention Item, a piece of prototype gear with punishing modifiers that you must carry into Chapter 3 or Chapter 4 and complete under harsh conditions. You can hold up to five Side Quest items at once, with 24 unique quests available in total.

Successfully completing an invention quest rewards you with a permanent unlockable version of that item plus 200 to 500 coins, with Chapter 4 completions paying out more. The guaranteed first quest is the Persuasion Device, which is also the only repeatable one; all others are one-time completions. If a cat carrying a quest item dies, the item is lost entirely, so you will need to donate another batch to Dr. Beanies to try again. Beyond side quests, Dr. Beanies also drives the game's deepest hidden content: he provides the Cryogenic Time Chamber, which must be carried into the Act 1 secret zone to capture the heart of the Throbbing King. Doing so repairs the time travel device and unlocks the Past and Future Act 3 branches, including Ice Age, Jurassic, Das Future, and The End.

Funneling cats with undesirable traits to Dr. Beanies is both smart housekeeping and the key to the game's most expansive endgame areas. Since mutated and disordered cats are often poor breeding candidates anyway, sending them his way clears out genetic dead ends while steadily building your quest item library. Lore-wise, Beanies reveals that his actions throughout the game are a form of revenge against God for the death of his beloved cat Stacy 35 years ago. He discards lab byproducts down a chute leading to The Core, and his story culminates in the construction of a reality-destroying device. His character design resembles Dr. Cool from Edmund McMillen's 2009 game Spewer, and his voice is based on a Dr. Insano impression by Harry Partridge.
