The last of the tadpoles that actually grew has become a teeny little frog. It'll be released into the pond at school tomorrow, despite much protest, along with the other little frogs. In the meantime, Hayley is very excited about her little froglet.
Just as an aside, we still have 2 tadpoles that haven't grown at all. They eat, they swim about, they seem perfectly happy, but in 4 weeks they haven't changed in the slightest.
