dude I will not give any thought to bedding beyond washing and changing the sheets, if somebody came in here and put SpongeBob bedding on while I was out, I would be unfazed

I know two seasons in my bed: When I share it and when I'm alone. It affects temperature and space. I have never thought about sharing it with deer or rabbits.

Halloween all year round same for spring.

If you want to change your Pokèmon bedding, go right ahead.

Too much work
