Happy Tree Friends: No More Cloning Around/Pets

Pets in this game act as an optional seventh team member. A pet will always sit on the backmost row alone, activating its skill at random, meaning that the player will have no control over it. Unlike the playable tree friends, pets have no health gauge (and no Special gauge either), so they can't be harmed, but a team will still lose if the participating tree friends in said team are all killed.

Pets aren't available in the early parts of the game. The "Pets" sidebar menu must be made accessible first by progressing far enough in the main campaign. After that, to revive a pet, you have to have enough Preserved Remains of said pet.

A pet can have its level increased by feeding them Pet Food (and spending some Coins). A pet starts with one skill, but it can learn more by ranking the pet up, which requires excessive Preserved Remains of the respective pet. A skill can be leveled up by using Pet Badges and Coins.

Much like the playable tree friends, pets have a "job" system of their own (in this case, it's referred to as "class"), which must be unlocked first to access.
