What Lived Under The Trapdoor In ' The Trap Door'?

A number of monsters appeared from under the trapdoor. The Protagonist in The Trap Door was Berk, a blue creature who was friendly and light-hearted, though sometimes a little careless, especially when he left the trapdoor open for monsters to escape, which Berk usually had to deal with. Berk was a servant to the master of the castle, also known as The Thing Upstairs, who constantly had jobs for Berk.

Berk had a pet spider named Drut and a best friend named Boney, who was a skeleton head.

The Trap Door was a claymation series, and each episode only lasted 5 minutes. It debuted in the United Kingdom in 1984 and ran on for 40 episodes, with every one of the characters being voiced by Willie Rushton.

All of  The Trap Door episodes have been available on DVD since 2005. Previously, some episodes were available on cassette, and a number of The Trap Door games have been available, including one for the Commodore 64.
