The kids have discovered that we are missing two Green Frogs.
Tubby-mora the largest frog is sitting looking smug, satisfied and like he has swallowed a tennis ball.
A quick check of Wikipedia discovers Tubby-mora's secret to his rather rapid growth.
Green frogs will consume anything that can fit in its mouth, such as: crickets, flies, fish, crayfish, shrimp, grasshoppers, smaller frogs, tadpoles, small snakes, birds, mollusks, moths, and their own cast skin. Tadpoles consume algae and water plants.[/quote]
We wonder no more what has happened to Tiny and Lulu.
Bwahahahaha yah! Tubby-mora King of the Pond.
