Growtopia Wiki

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

Starting a fight changes the background's weather to the Growganoth weather and permanently renders your Starship unusable, whether success or fail.
