The Pony Pals are excited about doing a nature watch in the woods. People say the black bears are making their way south and maybe the girls will be the first to see one up close. But they're also worried that Charlie will tell Tommy and Mike about their plans. Anna is on the night watch when she hears a rustling sound. Acorn is restless, pacing up and down. Could it be a black bear? Anna is terrified. Or is it just Tommy and Mike playing their usual annoying tricks on the Pony Pals?
