Cerberus in Steal an Egg

The Cerberus Egg is the Secret-rarity egg of the Volcano, and the pet inside it is Cerberus. Volcano is zone 6 of 12 on the wiki's Biomes list; the wiki lists its entry requirement as 700K speed, and the nests there are watched by the Cerberus.

Base income is $8M/s. Among the 8 pets tagged Volcano on the wiki that puts Cerberus at number 3 — Lava Dragon tops the Volcano at $100M/s. Remember the game multiplies this base by the size roll and by the mutation, so two Cerberuss can earn very different amounts.

With a colour mutation and no size bonus, the same Cerberus would earn roughly: Silver ×1.2 ≈ $9.60M/s, Golden ×2.5 ≈ $20M/s, Rainbow ×3.5 ≈ $28M/s (multipliers from the wiki's Mutations page; arithmetic is ours). Add a Giant (×3) or Huge (×5) size roll on top and the numbers multiply again.

Hatching it pays a one-off reward of +42k Speed, $800m, and the egg takes 2h to grow in the pen. That reward is the reason low-income eggs are still worth stealing early: the speed bonus is what gets you into the next zone.

Secret rarity is the badge tier: only 3.4 % of players had earned the 'Hatched Secret!' badge on 2026-09-13 (Roblox badge statistics).
