As soon as I saw this creepy baby I started making one for myself. The pattern can be no-sew or low-sew.

The size will depend on the yarn you use. I used a 20wpi yarn with 3.5mm hook for a 12” from tentacle to tentacle.

Materials:
Yarn: I used light weight yarn but you can use any yarn of your choice. White, Pink (muscle color), Light blue (or any other color for the iris)
Hook
Tapestry needle
Hot glue (optional, you can sew instead)
Safety eyes or felt (optional)
Metal wire or pipe cleaners
