My little pied girl is the same. She has outgrown her little blue bowl but she just loves it. She pushes all the aspen out of it and wears it like a hat on the floor of her tank half on and half off the UTH. She seems happy about it so I just let her be lol. I'll probably upgrade her to a medium RBI or Bean Farm hide in a little while but atm she likes to wear her blue bowl like a hat or sometimes like a turtle shell on her body with her head poking out thinking a rat is coming every time I walk by the front of the cage.
Lol I got that same ExoTerra hide in her cage too. She sits in it sometimes after eating but always goes back to the blue bowl.
