No need to worry that these mushrooms are poisonous. They're made from crown pumpkins and butternut, delicata, and carnival squashes (for recipes using the insides you scoop out, see our Squash and Pumpkin Recipes). 

Nestle the toadstools among rocks and trees, and add a jack-o'-lantern and snail. Your yard will be set for Halloween visitors.

Toadstool Pumpkins How-To
For the toadstools: Using saw, cut top off a round or squat squash for the toadstool's cap. Remove insides with fleshing tool. Insert a skewer into top of a tall squash (the toadstool's stem). Press "cap" squash, cut side down, onto skewer.

For the snail: Use a long, narrow-necked dark-green squash for the body (we cut off the base for shape). Using scissors, split the stem to create eyes. Using a linoleum cutter, Carve a swirl into the bottom of a small, round pumpkin (we used a 'Baby Boo') to make the shell. Secure "shell" to "body" with a skewer.
