Which Harpoon a Fish gamepasses are available?
Harpoon a Fish gamepasses cover bag space, fish growth, animal cash, mutation luck, and other boosts. The official Roblox pass listing checked on October 17, 2026 contains seven passes, with five marked for sale and two unavailable. Comparing the exact descriptions matters: a mutation boost, a cash multiplier, and shorter growth time solve different problems.
The five available listings are 2x Fat, +10 Bag, -50% Grow Time [PERMANENT], 2x Money [PERMANENT], and 2x Luck. 2x XP and VIP remain listed but are marked not for sale. The table below records that snapshot; check the price and availability shown by Roblox before purchasing.
Gamepass prices and advertised benefits
These details come from the official Harpoon a Fish gamepass listing. Prices are in Robux and reflect the API response collected on October 17, 2026.
| Gamepass | Listed price | Sale status | Advertised benefit |
|---|---|---|---|
| 2x Fat | 249 Robux | For sale | The name advertises a fat multiplier; the listing has no explanatory description. |
| +10 Bag | 79 Robux | For sale | Adds 10 bag spaces; the description says it stacks with VIP. |
| -50% Grow Time [PERMANENT] | 349 Robux | For sale | Cuts fish growth time in half. |
| 2x Money [PERMANENT] | 249 Robux | For sale | Doubles cash gained from your animals. |
| 2x Luck | 199 Robux | For sale | Doubles the chance of a mutation triggering when you harpoon a fish. |
| 2x XP | No current price | Not for sale | Advertises double XP from harpooning fish and the treasure chest. |
| VIP | No current price | Not for sale | Advertises 20% less growth time, 1.5x cash, five extra bag spaces, and a VIP nametag. |
An unavailable pass with a null price is not a free pass. The listing does not establish when either unavailable pass will return.
Match the description to the problem
Use the wording of each pass to distinguish its intended role:
- Inventory room: +10 Bag explicitly adds capacity. It does not advertise more aquarium slots.
- Waiting for fish to grow: the growth-time pass explicitly reduces that timer by half. Its description does not state a cash multiplier.
- Animal cash: 2x Money explicitly affects cash from animals. That wording does not establish that every reward or currency source is doubled.
- Mutations on catches: 2x Luck describes the mutation trigger chance when harpooning a fish. It does not publish an underlying percentage or guarantee a particular species.
- Weight progression: 2x Fat is named as a fat boost, while the game's official description connects greater weight with sinking deeper. The pass description is blank, so an exact gain formula or method cannot be confirmed from this listing.
Those distinctions help you inspect the right option without assuming that every multiplier affects the same part of the game. No purchase is needed to compare the descriptions and see which, if any, addresses the limitation you are encountering.
What stacking and permanent labels establish
The +10 Bag description explicitly says its bag-space benefit stacks with VIP. That is narrower than a general promise that all pass bonuses stack.
The growth-time and money passes include [PERMANENT] in their official names. The available descriptions do not explain how VIP's growth reduction interacts with the separate 50% reduction, or how its cash bonus combines with 2x Money. Avoid treating those pairs as a confirmed 70% timer reduction or a particular combined cash multiplier.
The listing also does not provide controlled before-and-after results. The benefits above are developer-advertised effects, not a claim of personal testing.
FAQ
What is the cheapest available gamepass?
In the October 17 listing, +10 Bag has the lowest for-sale price at 79 Robux. Its advertised benefit is 10 additional bag spaces.
Can I buy VIP or 2x XP?
Both were marked not for sale in the checked response. Their names and benefit descriptions remain visible, but there is no current sale price or confirmed return date in that response.
Does 2x Luck double my chance of catching every rare fish?
The official description specifically says it doubles the chance of triggering a mutation when you harpoon a fish. It does not confirm a multiplier for every rare species, spawn, or other reward.
Does +10 Bag expand my aquarium?
Its description promises bag space and says it stacks with VIP. It does not state that it adds aquarium slots, so those should be treated as separate capacities unless the live game explicitly says otherwise.
