The official August 5 Roblox update says a Fuse Machine was added to Capybaras VS Plants. Its recipes, required items, outcomes, and odds are not publicly documented by the source checked here.
Capybaras VS Plants Fuse Machine: what is confirmed
Capybaras VS Plants Fuse Machine information currently begins with one official update record. Roblox public game metadata, updated on August 5, says “Added Fuse Machine, New Boss + Bug Fixes.” That establishes that the Capybaras VS Plants Fuse Machine was added, not how a player should use it.
What the update does not explain
The source does not name Fuse Machine ingredients, recipes, input limits, success chances, outputs, prices, cooldowns, or interface steps. A Capybaras VS Plants Fuse Machine guide should not fill those gaps with a copied community recipe or a made-up progression route.
For now, treat the system as confirmed but partially documented. Check the current official Roblox experience page before testing it in-game, and use the news log for dated source changes. The boss page covers the other confirmed part of the same update.
