That's one of the reasons why I don't like to have clowns. But the kids like it.......
My first experience with clowns was like that too. It decided to host the zoas and eventually they went up the lorry.
Next time I try, it decided to sleep on one of the red pratas and it rub until the red prata face has a white patch......
At the moment, the pair I have, sleeps on the sandbed. But sometimes I see the bigger one playing near one of the pratas. Keeping my fingers crossed that they will stay on the sandbed at night.......
