There's non-stop fun as Barney and his friends learn all about opposites! Everyone helps Baby Bop understand concepts like up & down, in & out and high & low. Hey Diddle Diddle, the kids see that they can be big or little, but it's what's inside that counts! Then join in as Barney and his friends have a cool time on a hot day in a pretend winter-summer wonderland learning about hot and cold! There's always Tee-rrific teaching and fun when big dinos and small friends are around!
