Quadriddle*

- It is round, but not like a ball

- It has a hole in the middle, but it's not a doughnut

- It can make sounds, but it hasn't got a mouth

- What on earth can it be?

(I can't promise you a grand prize. But I'll see what I can think of if anyone guesses correctly - noone in their class did...)

*Don't know what a quadriddle is? Just a riddle that the quads came up with - for a school assignment, no less... And apart from the original being in Norwegian, this is exactly how it went!
