Maddie, Triggs and Dad are making a special cake for Granny. Dad is extremely careful about following the recipe, but Maddie has a slightly looser approach. Okay, a lot looser… Will their new bonkers cake pass the Granny test?

It's almost bedtime, but Maddie doesn't want to brush her teeth. Dad tells her all about the mysterious pearly whites (aka her teeth!), and how they sometimes start to sing when they're tickled. Really, singing teeth? It couldn't be true… Could it?
