Other Cosmic pets
Whale Shark guide
Two Cosmic pets live in Abyss Ocean, and the Whale Shark is the cheaper-to-wait-for of the pair. It earns $700K/s, slightly less than the Beluga Whale at $850K/s, but its egg finishes two minutes sooner.
Whale Shark vs Beluga Whale
- Income: Whale Shark $700K/s, Beluga Whale $850K/s
- Grow time: 10m against 12m
- Egg reward: +108k Speed and $70m against +126k Speed and $85m
- Base weight: 2,000 kg against 5,000 kg
The gap between them is about 21% in income. If you are cycling eggs through a limited number of pen slots, the shorter 10-minute timer is the Whale Shark's main argument.
Reaching the nest
Its egg spawns in Abyss Ocean, the seventh zone, which needs 2.5M Speed and is guarded by Moby. Nests refresh every 5 minutes. The $70m hatch payout covers more than half of the Golden Treadmill ($120M, +80 Speed per step), an upgrade that helps with the jump to Prehistoric at 18M Speed.
Numbers with mutations
The Whale Shark ranks 7th of 28 Cosmic pets and 80th of 198 overall (counting from the lowest earner). Applying the formula documented on the wiki, which it still calls beta:
- Golden: about $1.75M/s
- Rainbow: about $2.45M/s
- 100× base weight: about $12M/s
- Rainbow with 100× weight: about $41.9M/s
Rift relevance
The Rift Sacrifice lists the Whale Shark in the Hard tier for both Riftborn and Riftbeasts, so it is one of the tougher pets the banner can ask you to hand over.
