Mildred uses a broomstick that she finds on the beach (not realising it is Miss Hardbroom's) to fly out to the drifting boat, where she discovers not only Tabby, but the comatose Miss Hardbroom. Minutes after, they bump into Cat's Head Rock. Mildred ties the boat onto an odd-looking chunk of rock and falls asleep. When she awakens, she finds that Maud and Enid have discovered them.

Maud and Enid find her with her hair loose and a chunk of her hair tangled up with the brush in a huge mess. Ethel comes in and volunteers to help.
