Penguin

Penguins are one of basic enemies with simple AI. They try to get close to its target and attack it that way. Penguins are not too dangerous, but in small group they can became real threat.

AI
Penguins move using simple platforming movement. They're trying to move towards target and will try to jump if target is higher than them.

Threat
Penguins have basic threat calculation. That means they will attack target that made more threat to them. Threat does not decrease.

Penguins have group sharing threat that means attacking one will increase threat for all penguins in a range. This makes it easier for one player to tank whole groups, but also makes groups of penguins a lot more dangerous.

Tactics
Penguins have small amount of health. While fighting against one it can be easily killed before he can reach player.

They will begin to be more dangerous when in groups. 2 or 3 already requires some kiting. They don't hit hard so player can survive few attacks.

One AoE attack can kill whole group but player should be careful not to kill themselves.
