Roll Rat

Farmer · 15 maps

Overview

The Roll Rat is a small herbivore tamed for its unique role as a farmer and weight reducer. It provides an 80% reduction on Wood weight in inventory, making it highly efficient for wood-based resource runs. It can be airlifted by Karkinos or Quetzal for fast deployment.

Tamed via passive feeding, the Roll Rat excels at gathering plant-based resources and is commonly used to streamline early- to mid-game farming and base construction logistics.

Spawn Locations

Mod Maps

Roll Rats are passively tamed by feeding them while near the creature. The best food is Giant Bee Honey, which provides the fastest taming progress. About 22 units of Giant Bee Honey are needed. The process takes around 16 minutes and requires approximately 59 Narcotics to maintain torpor. Use the calculator below for your settings.
