Daisy has a special visitor at the vet – Tara the Tarantula! Daisy is really excited to see her, and thinks Mack will be too. What Daisy doesn't realise is that Mack is petrified of big hairy spiders. Mack doesn't want to let Daisy down, but he really doesn't want to meet Tara. Instead, he plays hide and seek with Magnus to avoid Daisy's calls.\n\nWhen Molly finds out about the tarantula, she asks Daisy if she and Suki can go too. Then Magnus asks if he can come along. Molly finally finds Mack and realises why he is avoiding going to the vet. It's up to Molly and Suki to show Mack that big hairy spiders aren't scary after all.
