Pattern is for a reversible pokeball that flips into a Blastoise pokemon.

Materials
Hooks:
For majority of pattern – 3.25 mm/US D/3
For chain stitches at opening – 4.00 mm/US G/6

Yarn:
Worsted weight yarn (I use Caron simply soft)
Pokeball colors - red (Caron: harvest red), black, white
Poliwag colors - Brown (Caron: Chocolate), blue (Caron: berry blue), white (Caron: white), black (Caron: black), tan (Caron: bone), gray (Caron: feathered gray)
Total yardage estimated by weight: ~120 yards, about half pokemon colors so quarter brown, little less than quarter in tan and a bit of the other colors. About the other half of the total will be the pokeball which is about half red/white and a small amount of black.

Some Fiberfill Stuffing, maybe a handful, sorry I did not measure.
