Spelling Bee is the tenth episode of The Worst Witch (2017 TV Series). It was first broadcast on CBBC and CBBC HD on 8 March 2017. It is preceded by The First Witch, and followed by The Mists of Time.
Everyone is called for an announcement, but Mildred doesn’t turn up because she’s trying to get Tabby off the roof after he got scared by a mouse. Miss Cackle magics Mildred and Tabby inside, and announces that Cackle’s Academy are competing against Pentangle's Academy in the spelling bee, a competition of spells and potions. Mildred and Ethel are chosen to compete for Cackle’s as they are next in the register, which Ethel is not too pleased about.
Miss Hardbroom starts training Mildred and Ethel for the completion, but Tabby makes a mess in the potions lab, so Miss Hardbroom has Miss Tapioca take Tabby to the kitchens to catch mice. Miss Pentangle arrives, and introduces her students, Sapphire Hailstone and Zac Hawthorn. Maud and Enid see that Mildred is upset over Tabby, and decide to help. They sneak into the kitchens and hear Miss Tapioca complain that Tabby is no good at catching mice because he is scared of them, and if he does not "toughen up" she will send him to the cats' home.
Mildred is studying in her room when Miss Pentangle appears, and offers her a doughnut. When Miss Pentangle refers to Miss Hardbroom by her first name, Mildred asks how they know each other, and Miss Pentangle says they used to be friends, until Hecate failed to show for the broomstick water-skiing display they were supposed to perform together. Miss Pentangle then magics Tabby to Mildred’s room for her.
When Tabby leaves Mildred’s room, Enid casts a spell on him to make him better at ridding the kitchen of pests, but the next morning, Tabby has attacked Miss Tapioca instead. As the Spelling Bee starts in the hall, Maud and Enid go the kitchens and attempt to catch mice for Tabby, to make him look good, but they just end up making a mess of the kitchen.
In the spelling bee, Cackle’s and Pentangle's are tied at three all with one round to go. During the intermission, Miss Pentangle offers Mildred a scholarship to her academy, saying that she has a ‘gift’. Miss Pentangle alerts the teachers to the fact that Mildred must compete in the final round, as she did not participate in the penultimate round. Mildred has to cast a weather spell - which she was studying with Tabby the night before. Meanwhile, Miss Tapioca returns to kitchen to find it in a mess, and blames Tabby, saying she’s going to send him to the cats’ home. In the spelling bee, Mildred successfully makes a weather spell, which rains over Ethel, and wins the competition for Cackle’s.
Afterwards, Mildred tells both Miss Hardbroom and Miss Pentangle that Miss Cackle wants to see them. They find themselves alone together, and make up with each other, hugging and saying they missed each other. Mildred is watching from the door. When Miss Hardbroom and Miss Pentangle ask if Mildred is taking the scholarship to Pentangle’s, she chooses to stay at Cackles. Mildred tells Maud and Enid that she’s staying, and Miss Hardbroom appears and gives Tabby back to Mildred. Maud and Enid tell Mildred she’s no longer the worst witch, and Mildred proceeds to drop her newly won trophy which is made of glass, shattering it.
- In the kitchen scenes, Tabby is clearly a different cat than in his other appearances. Tabby is normally a brown Tabby cat with white on his belly, legs and face, but in the kitchen scenes, the cat used is a different breed, more slender with different markings and no white.
