This pattern is from from a separate booklet, Knitted Amigurimi Sea Creatures.

It has the same pattern error noted by other knitters and the errata is found here:

If I were to do this pattern again I would start at the points of the sea star and increase to the wide point, put the points on waste yarn while I knit another, and then pick them all up again to finish. The pattern is written to pick up stitches from the cast-on edge which makes a ridge that stuffing can’t get rid of. it’s not bad but it would be better if it were smoother.
