How to get King Mammoth
Train until you have at least ~170K Speed, then go to Snow, zone 5 of 14, guarded by the Yeti. Steal eggs there and bring them back to your base to hatch.
Each egg that spawns in Snow has a 4.171033% chance to be a King Mammoth Egg. That means you need to see about 17 eggs for a 50% chance of at least one, and 55 eggs for 90%.
A King Mammoth egg takes 15m to hatch, and the wiki lists its reward as +22.4k Speed, $40m.
