Today after I was done mining I was walking back to my home I was started to go after some chickens in a plains biome because I ran out of food and I noticed at the corner of my screen I saw mooshrooms spawn. I need to know if this is a common bug so I can stop worrying about somthing bad happening to my world. Please reply if it is.
There is a slight chance of mooshrooms spawning in a non-mushroom biome, so no it isn't a bug. Don't worry about any danger to your map and enjoy the mooshrooms!
My friend has a TU1 world with Mooshrooms everywhere.
Stay fluffy~
