Pet Simulator 99 Abominable Yeti is the shared boss at Diamond Summit in Update 98. Players on the server fight it together, and your share of the damage affects your rewards. Feeding spare pets increases Yeti Power for better Diamond and rare-pet odds, including a chance at the Gargantuan Abominable Yeti.
Getting to the summit is only the beginning. The boss gives different pets from the mountain eggs, expeditions and leaderboard, so the best activity depends on what you’re trying to collect. Here’s the fight and its reward routes.
Where to find the Pet Simulator 99 Abominable Yeti
Climb Diamond Mountain by breaking Rubble Walls with your pets. Each new camp has an egg with stronger pets, and the sixth camp leads to Diamond Summit. The Yeti arena is at the summit, where the whole server can attack the same boss.
To fight the Pet Simulator 99 Abominable Yeti, send your strongest pets into the encounter. Everyone earns a share according to their damage, and more fighters add a party bonus. Stay until the boss falls so you receive your loot.

How to increase Yeti Power
You can feed spare pets to raise the boss’s Yeti Power, through levels up to Rainbow Shiny. Each level improves the chance of bigger pet rewards and increases the Diamonds paid out. The developer doesn’t publish a guaranteed number of kills or feeding amount for every rare drop.
The Pet Simulator 99 Abominable Yeti also creates a Diamond Party when defeated. If the fights are taking too long, try hatching stronger camp pets and using the mountain-only Damage Boost. Those boosts also help pets smash Rubble Walls on the way up.
What pets can the Yeti drop?
| Pet or reward | How it is earned |
|---|---|
| Huge Equinox Fox | Yeti fight and feeding |
| Titanic Amber Markhor | Yeti fight and feeding |
| Gargantuan Abominable Yeti | Rare Yeti reward or top-five leaderboard |
| Diamonds | Fight rewards and Diamond Party |
| Titanic Equinox Deer | Leaderboard prize, not normal drop |
The Pet Simulator 99 Abominable Yeti fight gives a chance at Huge Equinox Fox and Titanic Amber Markhor. The ultra-rare Gargantuan Abominable Yeti is also a possible fight reward. All of them depend on luck rather than a fixed number of fights.
How to get the Gargantuan Abominable Yeti
Besides the rare fight reward, the Yeti leaderboard awards Gargantuan Abominable Yeti to the highest-ranked players. First place gets a Rainbow Gargantuan, while positions two to five get a regular one. That is a ranked prize, not a guaranteed pet for fighting the Yeti once.
The Pet Simulator 99 Abominable Yeti leaderboard also distributes several Titanic Equinox Deer variants and Huge Climber Goat lower down. Damage contribution determines your score, so continuing to fight matters even when the single-boss drop doesn’t go your way.

Can Yeti fights earn the free Huge Hiker Raccoon?
Fighting the boss earns Season Tokens alongside breaking loot and hatching eggs. The free Season Pass awards Huge Hiker Raccoon at Tier 4, giving you another goal while chasing boss drops. No premium Forever Pack or paid Exclusive Egg is needed to earn that Huge.
If you’re focusing on the Pet Simulator 99 Abominable Yeti, this is useful progress even when you’re unlucky with rare pets. Keep collecting Season Tokens, and check your pass rather than assuming it levels only through egg hatching.
Yeti rewards versus Secret Trails
Six secret Mountain Trails open at the summit and have their own chests and rare final egg. Titanic Expedition Leopard and Huge Climber Bear belong to trail rewards, not ordinary Yeti fight loot. Huge Expedition Wolf is from hourly expeditions instead.
For the Pet Simulator 99 Abominable Yeti, concentrate on dealing damage, upgrading Yeti Power and staying for the kill. If you want leaderboard rank requirements, the Yeti leaderboard guide lists the prize brackets separately.
