Growlactus serves as a boss in Startopia. It can be fought by traveling to the Galactic Nexus, and reaching 25,000,000 Star Miles along with having a minimum ship rating of 12,000.

Starting a fight changes the background's weather to the Growganoth weather; succeeding will allow the player to journey to the Heart of the Galaxy, while losing will allow them to journey to the Desolated Waste. Previously, fighting Growlactus permanently renders the player's starship unusable, whether they have succeeded or failed.

Trivia

  • The name "Growlactus" was inspired by Galactus, a fictional cosmic entity appearing in comic books published by Marvel Comics.
    • The appearance of Growlactus as described in-game, however, bears little to no resemblance to the character it is based on.
