This pattern is an homage to Mudkip, a character from Pokémon.
The hat has variable sizes on offer to cover an approximate age range of 1-12 years. The hat can be adapted to larger sizes by scaling up the hat and the top fin.

The pictured hat is the smallest size - 1-3yrs.

I have used Stylecraft Special Aran for the hat and Stylecraft Special DK yarn for the eyes and other hand stitched parts. Any comparable weight yarn should ok to substitute in.

You only need less than 10g of Black & White DK yarn. You will need less than half a ball of orange yarn for the gills or light blue for the ribbed brim. You will need less than one ball of blue yarn for the hat itself.

The eyes have been crocheted, but felt pieces can be used if preferred.
