The Cuckoo Clock

The Cuckoo Clock is a magical clock that allows people to travel in time. It appears in the twenty-eighth Goosebumps book, The Cuckoo Clock of Doom, and its television adaptation.

History
Michael's dad says that the clock was built in 1800 in the Black Forest of Germany. He said that legend has it that a strange old man who built the clock had magical powers and put a spell on the clock. If someone can figure out the secret, he or she can go back in time. This secret is revealed to be in the cuckoo bird itself. Michael decided to (as a way to get back at his sister Tara), twist the cuckoo's head backwards, but found out the hard way that doing so reversed the flow of time and eventually regressed his age back to his 12th birthday and his 6th birthday even where he was a baby. Only by returning it to normal does time resume its natural course. Also, as suggested by the The Cuckoo Clock of Doom, it is possible to erase events from one's timestream by removing specific year markers from the side of the clock. Before the cuckoo clock was bought, it was in an antique shop called Anthony's Antiques owned by a man named Anthony (Which is obvious) who didn't want to sell it because there is something wrong with it until now he decided to sell it.

Physical appearance
The clock is mostly black. It is decorated with silver, gold, and blue designs, scrolls, carvings, knobs, and buttons. The clock has a white face with gold hands and gold Roman numerals. There are secret doors hidden under the paint designs, and a big door in the middle of the clock.

On the right side of the clock, there is a dial starting at 1800 and ending at 2050. There is only one hand on the dial and it points to the current year. Beneath the dial is a little gold button set into the wood.

Trivia

 * Although the clock is referred to as a "cuckoo clock" in the title of the book The Cuckoo Clock of Doom and by its characters, the clock more closely resembles a grandfather clock.
 * In the film, however, the clock is correctly depicted as a cuckoo clock.
 * In Goosebumps: The Game, if you remove the 1988 plate from the clock, you will hear a scream (Which is possible a scream from Tara considering the fact that she was born in 1988).
