Goomba

Goomba was a "tree god of tremendous power and wiles". He resembled a piece of bamboo.

The Eighth Doctor believed that Goomba came from another dimension, and that he arrived on Earth at what humans called the dawn of time.

Goomba then landed in prehistoric China and planted himself in a forest of bamboo.

Millions of years later, Goomba was made into a wickerwork chair and shipped to a garden centre in Manchester. Peter's family bought the chair as part of a patio set and put it in their backyard. Goomba took possession of Peter's father and began amassing wooden objects. When Peter's father held a garden party, Goomba possessed the guests and began absorbing wood into himself. After a few days, Goomba had gained a large group of followers and a body composed of mostly furniture which as high as a beech. At Goomba's apotheosis, he planned on sacrificing all of his followers so that he could slip back into his home dimension. The Doctor lit a fire at Goomba's feet, destroying his body and releasing his hold on his followers. (PROSE: The Wickerwork Man)
