Upgrades Guide
Pumps, aura, backpack space, and walk speed compete for the same cash. Buy what matches the current bottleneck.
By Bloxron Editorial Team · Last updated
What upgrades fix
Buy what fixes the bottleneck. Pump raises click water. Walk speed helps on long vertical maps. Display stand raises aquarium income. Backpack stops fish from despawning. Aura multiplies drain after you already have a strong pump. Stage gates that need more power are on progression; pet multipliers stack on pets.
Deep links: progression, pets.
What to buy first
Pump jumps first, then bag or display when fish choke, then aura once the base is real.

| Pump | 1 - first | Biggest click water jump early |
| Walk speed | 2 - QoL | About $10K early; long vertical maps |
| Display stand | 3 - income | Show slots 7 to 8 to 10; aquarium can reach about 12 fish late |
| Backpack slot | 4 - when full | Early slot ~$5K; later slots ~$45M / ~$80M; late bag about 10 to 12 slots |
| Aura | 5 - after pump | White to Green to Blue; multiplies existing click water |

Backpack slots vs aquarium displays
Bag holds caught fish. Display stands hold equipped aquarium earners. Do not confuse the two shops.
- Backpack. Inventory slots for fish you just picked up. Early +1 slot is about $5,000. Later expansions hit about $32K, $150K, and $320K. Late game reaches about 10 to 12 bag slots. Full bags can lose fish.
- Display stand. Aquarium show slots for equipped income fish. Expand from about 7 toward 8 and 10. Endgame tanks can hold around 12 fish. This is not the backpack upgrade.
Aura multipliers
Aura multiplies an existing pump base. Buy after a real pump jump, not before.

FAQ
Can I skip pumps in the chain?
Yes. The shop can let you buy ahead with a confirmation popup. Buying in order avoids surprise prompts.
Is Sunflower worth it?
Yes early on. It is the first big jump from the starter pump at $3,000 with a ×30 water multiplier.
Aura or pump first?
Pump first. Aura multiplies what you already have. A weak base times aura still feels weak.
What is the training zone?
Rebirth unlocks standing pools that add water passively. Level gates and pool multipliers are on the progression page.
Is Demon the last cash pump?
Yes. Demon at $22.5M (×12,500 water) tops the cash ladder. Higher pumps such as Blue Mushroom, Ice Penguin, Planet, and Mecha Gaioka are Robux-only.
What is Lgnisthul?
An OG-rarity pump at ×7.5 water. It is not part of the normal shop ladder and has no listed cash or Robux price on the standard pump chain.
What is Mecha Gaioka?
The highest-priced Robux pump at 799 R$, added mid-August 2026. It sits above Planet (759 R$, ×4M water) in the shop.
