Mushroom mounting...???

[Blindzy]

Hello all,
So I traded for a nice quarter sized bounce mushroom about 3 weeks ago. I have had it in a container with rock rubble since then and it still has not attached to a rock!!! It has attached to the side of the container twice where I have had to go in and remove it and try again. What can I do here to get the dang thing to attach to rock??

you can try sm tiles, or smooth surface rock rubble
