Yuko and mini Yuki can be made of any kind of yarn. These 2 cuties were made of the same pattern but the different is the size of hook. My pattern called for 2.5mm hook for Yuko and 1 mm. crochet hook for mini Yuki and stuffed with fiberfill. All pieces are crocheted in the round.

Finished size for Yuko is about 2.5” x 3” and mini Yuki is about 1.5” x 2”, but you can also use bigger size of crochet hook to get the bigger octopus.
