I used BBs wire and gorilla glue to make the base and stem 

I used foam balls for the actual plants face

I painted the foam with acrylic paint and moss to cover the BBs in the pot. I also glued fake leaves to wire and wire vines.

I then painted the mouth pink and added teeth.

The beginning of plant #2

Plant #1 finished. Glued more fake leaves to back and added a tongue that also moves.
