An Experimental Egg pet
Three Headed Chicken is the middle result of the Experimental Egg, tied to the Experimental banner in Dr. Scramble's Laboratory. The Laboratory replaced the Rift Trade-In Machine in Update 6; Experimental draws from Cosmic, Cherry Blossom and Titan Temple eggs. Update 6 also made it possible to trade eggs in directly and buffed pity so it guarantees the top reward.
The egg's line-up:
- Wheel Hamster, Mythic, $450K/s
- Stacked Turtle, Cosmic, $12M/s
- Three Headed Chicken, Cosmic, $165M/s
- Eyeball Crab, Secret, $825M/s
- Dreadstinger, Eternal, $2B/s
The jump from Stacked Turtle to Three Headed Chicken is almost 14x, so landing it on a pull is a real step up. The wiki doesn't record a grow time or hatch reward.
Light pet, heavy numbers
Its base weight is only 24 kg. Overall, 61 of 198 pets earn more. Estimates with the formula the wiki documents:
- Golden: about $412M/s
- Rainbow: about $578M/s
- 10x base weight: about $683M/s
- 100x base weight: about $2.82B/s
- 200x base weight: about $3.91B/s
- Rainbow at 100x weight: about $9.88B/s
The Experiment Shop's Scrambled Mutation (475 Samples, x2.75, 10% chance) would bring a plain Three Headed Chicken to about $454M/s. A 10x copy alone is within reach of a plain Skeletal Terrorbird, and a 100x one would beat Eyeball Crab.
