Stag in Steal an Egg

Stag hatches from the Stag Egg, a Secret-rarity egg found in the Cherry Blossom. Cherry Blossom is zone 10 of 12 on the wiki's Biomes list; the wiki lists its entry requirement as 2.5B speed, and the nests there are watched by the Oni Tiger.

The wiki lists its base income as $145M/s, which ranks it 3rd of the 8 Cherry Blossom pets by base rate — Kitsune tops the Cherry Blossom at $1.8B/s. Base rate is what a normal-size, un-mutated hatch earns; everything above that comes from the size roll and the colour mutation.

With a colour mutation and no size bonus, the same Stag would earn roughly: Silver ×1.2 ≈ $174M/s, Golden ×2.5 ≈ $362.5M/s, Rainbow ×3.5 ≈ $507.5M/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 +4.8m Speed, $14.5b, and the egg takes 3h 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).
