The Trap Door Collection

The Trap Door Collection is a compilation game that was released by Alternative Software on the Sinclair ZX Spectrum in 1990; it includes both of the ZX versions for Piranha's Trap Door games:
 * The Trap Door (1986)
 * Through the Trap Door (1987)

Alternative Software had also rereleased both games individually for the ZX in 1988 along with Piranha's other licensed title of Yogi Bear - which later went on to receive two sequels by Hi-Tec Software, Yogi's Great Escape and Yogi Bear and Friends in: The Greed Monster, the second of which also starred several other classic Hanna-Barbera characters of the early 1960s many of whom also went on to get games of their own.
