LOL, we have Polka Bats too. My kids memorized Eliza's Pockets (dd 8) and Snails (ds 11) for their memory pieces when trying out for a play this summer. We had a ton of fun with those!

My son started reading Redwall books at age six. They have great vocabulary and the violence is minimal, though most are about battles between the good creatures and the bad . Mice, badgers, and hares are good, weasels, rats, and foxes are evil...
