The New Worst Witch

The Bewitching of Mona Hallow (1x10)

:

Its Hazlemass, a special Hedge Witch ceremony, but to Cressie's disappointment, Miss Hardbroom tells her that Cackle's does not celebrate Hazlemass. Hettie and Mona decide to help Cressie celebrate it anyway, but when the girls leave the celebration cake unattended, Belladonna puts a bewitching spell on it. Mona persuades the others that she can look after the cake without touching it. She just has a taste and immediately becomes enemies with Hettie and Cressie.
