I got the idea for these Quiet Critters from The Teaching Chick blog via Pinterest.  They are a dream come true for bus dismissal time!  I pass them out at the end of the day, and students bring me their Quiet Critters as their bus is called.  If they are quiet during bus dismissal I give them a stamp or a sticker.  Works like a charm!  I found a Foamies brand kit that included the pom poms, googly eyes, feet and hats.  I put them together using a hot glue gun, and I they have held up great!  I highly recommend using these in your classroom!
