Hime Chan's Ribbon

Pokota’s SOS from the Stormy Mountain (1x15)

:

Hikaru heard Pokota speak at the cabin on a school ski trip. She later decided to go skiing by herself, with Pokota in her pocket and headed for the back woods ignoring "danger" sign and fell down the cliff. Hime-chan must risk revealing that Pokota is alive by putting the ribbon on and going out to save Hikaru.
