Mutation stats, not speed boosts

One accessible publisher reports these multipliers

Only reported by FFBooyah (2026-10-23): Silver 1.25x, Golden 1.5x, Rainbow 2.25x, Magma 4x; Spectral is described as unobtainable. The same article lists sizes from Tiny 0.25x to Colossal 10x and reports additive combination, including Magma plus Colossal at 14x. GAMES.GG could not be read during this review and is not counted as independent confirmation. These are reported figures, not a verified formula. A RideADinoRoblox devlog chapter uses the title Mutations and Evolution; developer ownership of that channel was not authenticated from the game page. The spelling mutaation is a search misspelling.

Sources disagree: the AllThingsHow beginner article dated 2026-10-21 says no mutations in game A, while its earlier 2026-10-19 chest article describes Magma. Game B explicitly describes speed mutations; its description does not establish that game A uses the same system. See which game and Meteor Chest evidence.
