>>11945603As long as you explain to the Larvesta that the tree house is not to be burned down, I think it's a great idea.
I have small little enclosures for all the Larvestas I haven't been able to find homes for yet, and after teaching them not to burn it, they seem to have a lot of fun playing together in it.
They've even managed to integrate a few Sewaddles into their little home.
So I know making them a house can work, it just takes a little work.
