Errata:

For the Bunny Foot

Row 51 has a stray k1 in it
Row 55 should be a repeat of row 51

So the foot is as follows:-

Row 51: In contrast colour k1, inc 1, rep from to end of row (15 sts)
Row 52: Purl
Row 53: K1, inc1, rep from to last stitch, k1 (22 sts)

The foot can also be knit the same as the paw if desired.
