Grow a Pet Fighter does sell a game pass: 2x Money at 199 Robux

September 10, 2026

Correction to what this site said before 10 September 2026. We had recorded Grow a Pet Fighter as selling no game passes. It sells one: a pass called 2x Money, priced at 199 Robux, on sale now, created on 18 August 2026 and last changed on 1 September 2026.

The mistake was ours and it is a specific one, so it is worth writing down. We had queried the older endpoint at games.roblox.com/v1/games/{universeId}/game-passes, which answers 404 Not Found for this game. A 404 looks like an answer but is not one, and the proof is that the same URL also answers 404 for other, far larger games that certainly do sell passes. The endpoint that works for signed-out readers is apis.roblox.com/game-passes/v1/universes/{universeId}/game-passes?passView=Full, and it returns this game's pass list as a normal response.

An empty result and a failed request are different things, and we had treated one as the other. Our badges-and-passes guide now states which endpoint produced which figure, and the systems table on this site carries the pass as a measured row rather than an absence.
