“KehaanPets” is a new mod for 1.16.4 and 1.12.2. This mod adds a “pet” that you can have in your inventory. Right clicking it will spawn a random craftable item, and consume soul sand. There is a time limit on when you can use it which by default is every 10 minutes. You can change in the configs what the pet can eat, and how often it allows you to eat it.
