Singing bats and meet the really, lonely iceberg!

Bats might seem scary but they're incredible animals - and they play an important role in our environment. Hannah Van Hesteren is an expert from the Bat Conservation Trust and she's answering all our questions about bats, like are they really blind and can bats sing

Plus, we shoot off to the Sun with the Space Cadets, learn about a very venomous snail and meet the lonely iceberg travelling the world’s oceans by itself!
