This is my own favourite. A Crochet Patterns of a little bathing bear in one PDF document. The pattern is easy to crochet.

The pattern can be made using any yarn you wish. Adjust your hook size so that your stitches are as tight as possible. I have used acrylic yarn and
Crochet hook = 1.75 mm.

Finished Bathtub is about 4 inches / 10 cm.
Finished bear is about 2.5 inches / 6 cm sitting.
