"Fuuko used to hand them out as a way of inviting people to onee-chan's wedding, and would carry them around in a bag!"

"Sometimes, Fuuko gives the starfish to nice people here. Maybe later Fuuko could start using the starfish as a way of inviting people to the Starfish Festival!"

Yup, Starfish Festival.
