Pets

The pet menu in the Shop. Woody is currently equipped.

Pets in Zombs.io are minions that fight along with the player. Pets can be obtained through the Shop. Only one pet can be equipped at a time.

Mechanics

Growing and Evolving

Certain actions, such as killing enemies or harvesting resources around the map, grants experience to the pet. Note that when attacking enemies, the pet does not need to deal the killing blow to gain experience. After a certain amount of experience gained, the pet levels up and its health is fully restored. The current maximum level is the current wave - if the pet kills any enemies beyond this, he will not gain any experience.

Upon reaching certain levels, the pet can be evolved to the next Tier, increasing its stats (such as health, strength, and speed), after spending the required number of tokens. These tokens are obtained from monsters and bosses. Once you press the Evolve pet button, your pet will evolve after a several second wait. It is important to note that pets will still gain levels even if not evolved right away.

Fighting

The pet will only attack when the player attacks first. Once a target is killed, the pet will automatically pick another one if the player keeps attacking. While moving to the target to fight, any zombie in range will be attacked by the pet. The pet will stop fighting and follow the player if outside a certain distance, and will teleport to the player at a distance of around 20 tiles. In case he is focused on an unwanted target, use the whistle () available in the action bar.

Your pet will inevitably take damage, especially if it is a melee attacker like C.A.R.L. The active pet can be healed in any moment with a Pet Potion (), which can be bought in the shop. Any dead pet can be revived from the shop page; simply click the purple Revive Pet button and your pet will return within a few seconds.

Remember that enemies always aim at the closest object; if this object is the pet, then the pet will be the target.

Pets List

C.A.R.L.

Tier 1 C.A.R.L.

The first added pet, obtainable by sharing the game to Facebook and Twitter. He attacks using a melee spear. With the increase in damage, at higher levels C.A.R.L will also move faster, which at the highest level players cannot out run.

[*] Note that this value isn't exact and slowly increases based on the wave and tier.

Extra info: Tier 8 C.A.R.L. is the only C.A.R.L. type who can heal itself killing zombies, unlike the other tiers.

Tier 1 Woody

Woody the Harvester

The second pet. This pet can only be obtained by subscribing to the official YouTube channel. One thing that worth noticing is that when gathering several resources at the same time Woody will always go for WOOD instead of stone, which could lead you into a lack of stone.

Ghost _{(info may not be accurate)}

Yang (the game dev ) confirming that the Ghost Pet was intended for testing purposes.

Tier 1 Ghost Pet and its projectile.

How the pet would look in the game

There is very little to no info about the existence and functionalities of this pet in the game. First of all, it has only one tier (probably). Some other known thing about this pet is that it was used as a test pet in the game developement.

Based on the existing assets in the Zombs.io's sources, it seems to be a ranged pet, being able to shoot white projectiles. Interestingly, the site has a custom title - "deetghost" & "deetghostammo", while accessing the ghost pet assets (), unlike the other assets that have the title defaulted as the link, which means out little ghost pet has a name....? Deet? DeetGhost?? deeznuts????.

Talking about projectiles, there is some info about C.A.R.L. (which is the first pet added into the game) that contains some projectile stats that weren't removed, i suppose. It contains projectile lifetime, velocity, aoe, etc., and obviously everyone knows that C.A.R.L. isn't a ranged pet to shoot projectiles and it does NOT deal aoe damage (like a cannon).

Tier	Image	Stats
		Cost	Health	Damage	Ranged	Projectile
						Lifetime	Velocity	AOE	AOE Radius	Collision radius
I		Unpurchasable	?	?	true	1s	60	true	250px	10px
The AOE radius (250px) is equal with the cannon's AOE range & the Velocity (60) is equal with the T1 Arrow Tower's projectile velocity.

Some data in C.A.R.L.'s stats file, which probably are leftovers from the Ghost pet.
