The lad found bugs galore with the other children.
He traded one of his toads in order to keep some of the bugs. All types of caterpillars. He gave them a whack of green stuff to eat so they should be okay for a spell. The lad usually releases them in about three days so no lasting harm done to the wee critters.
The highlight of our walk was the young lad from the other family used my son's bug net to catch a big green frog. Hubby took a pic with his camera so I don't have it here to show you. :)
We also found a small toad that we took home with us. The lad liked this since now he still had a toad even if he gave away his bigger one. :)
