Tralaledon guide
Tralaledon is the stronger of Prehistoric's two Secret pets and, oddly, the lighter one. It earns $32M/s with a base weight of only 1,000 kg, while the T-Rex earns $25M/s and has a base weight of 7,500 kg.
Getting the Tralaledon Egg
- Biome: Prehistoric, 8th in the biome order
- Speed needed: 18M
- Guardian: T-Rex
- Grow time: 3 hours
- Reward on hatch: +480k Speed and $3.2b
The $3.2b covers The Freeze Treadmill (3B, +100 Speed per step) with a little to spare, which makes this egg a direct route to that upgrade.
Why the low base weight matters
According to the wiki, bigger eggs carry a higher value multiplier but make you slower while carrying them. Because income scales with weight relative to the pet's own base, a Tralaledon reaches high multiples of its base weight at much lower absolute weights than a T-Rex does. A 100× Tralaledon is 100,000 kg; a 100× T-Rex is 750,000 kg.
Estimated income from the wiki's documented formula (marked beta on the wiki):
- Golden: about $80M/s
- Rainbow: about $112M/s
- 10× base weight: about $132M/s
- 100× base weight: about $548M/s
- 200× base weight: about $758M/s
- Rainbow with 100× weight: about $1.92B/s
Placement
It is 2nd of 8 in Prehistoric, behind only the Eternal Mosasaurus ($180M/s, 6-hour egg). Among Secret pets it ranks 10th of 35, and 121st of 198 overall, counting from the lowest earner.
Choosing between Tralaledon and T-Rex comes down to the clock: 30 extra minutes of growth for 28% more income and +60k more Speed on hatch.
