Snow Biome

Snow sits farther along the map, behind a 170K Speed requirement, and its nests climb from Rare all the way to the first Eternal egg in the game. Its guardian is the Yeti, a Secret pet worth $5M/s with an egg that grows for 1 hour 45 minutes.

The Snow roster

• Penguin (Rare, $140/s, 45s) and Walrus (Epic, $600/s, 1m).
• Polar Bear (Legendary, $7K/s, 2m).
• Sabertooth Tiger ($35K/s, 4m) and Mammoth ($42K/s, 5m), both Mythic.
• King Mammoth (Cosmic, $400K/s, 15m).
• Yeti (Secret, $5M/s, 1h 45m).
• Ice Dragon (Eternal, $65M/s, 4h).

The Ice Dragon is the first Eternal you meet in biome order and the lowest-earning of the 24 Eternals, which still means 13 times the Yeti's income. Its 4-hour egg is the longest wait so far.

Covering 530K Speed to reach Volcano

Volcano needs 700K, so the gap from Snow's entry point is 530K. Snow's rewards run from +12.8k (Penguin) to +32k (Ice Dragon), and one of each egg adds only 160k. Counting eggs alone:

• 42 Penguin eggs, at about 284 Speed per second of growth, the best ratio in the biome.
• 28 Mammoths, or 17 Ice Dragons at 4 hours apiece.

Eggs alone are a slow route here, so this is where purchases take over. One Mammoth reward pays $4.2m, close to the Celebrity Treadmill's $5M price (+30 Speed per step), and a single King Mammoth reward ($40m) covers the Golden Trail (3.5×, $30M).

Snow pets in the Riftborn banner

Snow is one of the four biomes the Riftborn banner draws from. For the Rift Sacrifice, the wiki lists:

• Easy: Penguin.
• Medium: Walrus, Polar Bear, Sabertooth Tiger and Mammoth.
• Hard: King Mammoth.

Yeti and Ice Dragon are not on the sacrifice lists. With the wiki's formula, a Golden Ice Dragon (×2.5) would earn around $162.5M/s, more than any base Volcano pet, so a lucky mutation roll here can carry you well into the next biome.
