These totally rock.  The kids LOVE playing with them, putting them in size order, making their prey, etc.  They just love them and so easy to make.  I got this idea from Bundles of Love.  Have I mentioned that pinterest is the best thing since sliced bread?  FOLLOW ME HERE!

Anyway, just collect toilet paper rolls, fold in the sides at one end and tape.  Then paint and embellish.  Voila!  So much fun.
