The snake body is made from 2 feet of 1 5/8 inch diameter plastic tubing. The head was formed using craft foam, glue and paint.
The angle support to hold the snake upright was 3d printed:
but it could be cut from wood or cardboard.
Froggy doesn't like to admit it, but if you look closely, you'll see a yellow stripe down the back.
Add another screw at the end of the tail to support the snake body.
