Pet-Pets or duplicate pets are extra pets that give you extra boosts. Below your air tokens/candy canes is a GUI button on the right where it will show two scoops, click it and you are in the Pet-Pets menu. You can obtain Pet-Pets from the shop in the Pets section from clicking "Buy as Pet-Pet" on a pet and also getting the same pet from a tier Gachapon. Since Update 18, you can now make rainbow pets (you have to have 10 of the same pet to make it rainbow) that have stats 10 times better than the original pet.
- Pet-Pets can be made into rainbow pets, while your main Pet cannot turn into a rainbow pet.
- When opening a tier gachapon, if you get 2 of the same pet, you will get one as a pet-pet.
