I was hoping it was same as pancake stack. It doesnt appear to be. I tested it for around 10 minutes and at times i questioned maybe it has a small pull, but i think it was just the normal rotation of the pets. I moved it to different corners of my garden, it didnt seem to affect them.

Also if i placed a single pancake stack they would never even get close to the egg yolk mat, while obvioulsy hovering around the pancake stack most the time

So save your pass points for now, maybe mutliple of them will do something but the fact that its only mythical and pancake stack is prismatic. I think its just a regular decoration that is way over priced in the store
