Hair Bobbles as Toys?

I bought my daughter some hair bobbles to pop in her advent calendar.  I assumed we'd need some in the near future and as it's tough to find small inexpensive items so I was running short on ideas.  I hoped she'd like them, bright colours an' all but I wasn't actually expecting her to play with them.

They live on a neglected teddy elephant's trunk.  Today she has demanded the elephant and has then spent the last hour - yes I said hour - pulling them off the elephant and pushing them onto her arm.  Pulling them off and putting them back on.  One full hour of peace and quiet - TV and guilt free.

I figured this was worth sharing . . .
