Pet zombies

Ever since the "Dead town" apocalypse struck, zombies started growing in numbers. This also affected pets but in a lower rate. Pet zombies are introduced in day 10 in survival mode. Both pet zombies come in 2 variants. The pigeon zombie and the dog zombie. These zombies rarely spawn and has slightly has less hp than a zombie. So, let's talk about the pigeon zombie. They are small flying zombies who attack from above and having the ability to fly through walls to attack the player. The dog zombie goes the same speed as a pigeon and nothing really special about it; besides of how green it is. The purpose of these zombies is to confuse or scare the player with it's speed and their looks.
