Leprechaun Woes

Oh, no....The leprechaun returned to the preschool classroom.  He left things scattered all over the classroom.  While the children were picking up and putting away his mess, one of the girls said that someone needs to teach the leprechaun to put his things away when he is finished playing.  He left a leprechaun gold, beads, and other fun items in the sensory table and asked the children to guard his leprechaun gold.  The children decided that they needed to catch the leprechaun.  They worked in groups and built elaborate traps in the hopes of catching him.

Who made this mess?
