Gargantuan Pets are a type of pet in Pet Simulator 99. They are larger than titanic pets in both size and power. They can only be acquired from Exclusive Eggs, Gargantuan Machine Eggs, and occasional Events. They always have the Exclusive rarity, along with 5 question marks to describe their power. In the inventory, their icons are 2x bigger than titanic pets, and will always appear at the top of the inventory.
When riding a gargantuan pet, up to 4 other players can ride the pet as well, but they can't control the pet.
Gargantuan pets have a Ground Slam ability, which allows the pet to deal AoE damage to breakables within their radius.
They were first teased in a post from X (formerly Twitter)[1] with a like goal. While the post never achieved the goal, by Update 39, Gargantuan Santa Paws was added regardless.
Hatching Cutscene
When a player hatches a gargantuan pet, a hatching cutscene is displayed for everyone in the server. The sky turns dark, the egg the pet is hatched from levitates into the sky, and a crack in the sky emerges. After some time, the player will ascend to the crack and ride the pet they hatched to the ground. If the pet is golden, rainbow and/or shiny, this is displayed on the pet as well.
All gargantuan pets have the same cutscene.
