T-Rex (Secret rarity) belongs to the Prehistoric zone. Prehistoric is zone 8 of 12 on the wiki's Biomes list; the wiki lists its entry requirement as 18M speed, and the nests there are watched by the T-Rex. You get it by carrying the T-Rex Egg back to your pen.
At $25M/s base income, T-Rex sits 3rd out of 8 in its zone — Mosasaurus tops the Prehistoric at $180M/s. The listed figure assumes no mutation and a normal weight.
With a colour mutation and no size bonus, the same T-Rex would earn roughly: Silver ×1.2 ≈ $30M/s, Golden ×2.5 ≈ $62.5M/s, Rainbow ×3.5 ≈ $87.5M/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 +420k Speed, $2.5b, and the egg takes 2h 30m 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).
A mutated or oversized T-Rex earns a multiple of its $25M/s base. Pick T-Rex in the Steal an Egg calculator to apply the wiki's mutation and size multipliers.
