S1, E3: It's time for the presentation of the kittens which will sit decoratively on the end of each girl's broomstick when they fly! When Mildred's Tabby can't even cling on to her broomstick, Ethel lays into Mildred about how hopeless she is, Mildred has been pushed too far, & turns Ethel into a piglet! She escapes, & the race is on to catch it & turn her back, before Miss Hardbroom finds out!
