i checked the wiki for their preferred foods:
Preferred Food[edit | edit source]
When moving, Gachas prefer Berries than Meat, they don't eat Stone while moving, so watch their food meter when traveling long distances and supply it manually with Berries, which Gachas don't harvest, or Meat.
When static, they eat everything and prefer a combination of Stone or crafted items and Snow Owl Pellet
Also Element, all sorts of crafted items, Element Ore, ammunition, as well as resources like Metal, Stone, Flint, Wood and others are accepted. This
