Scooby-Doo and Scrappy-Doo/16-bit

When this game was redesigned for the Commodore Amiga by Gary Antcliffe (by taking an existing game named "Stig the Rat", and replacing the main character's sprite for marketing reasons), five extra levels were added, an original song by Paul Loraine was composed, and the storyline was changed:

Our heroic trio, Scooby-Doo, Scrappy-Doo and Shaggy, are enjoying a well earned break aboard the pleasure cruiser "Bluebell", away from the  the haunted houses, ghosts and villains.

As Scooby lies dreaming of munching his way through a second box of Scooby ''Snax, a menacing black shadow looms above. In a flash, the evil Baron Von'' Drak whisks the trembling Scooby and Shaggy from their sun loungers carrying them far across the ocean to his lair, the "Isle of Sorrows".

''And so another adventure begins. Scrappy-Doo, our hero, remains stranded on'' ''the "Bluebell" and must save the day. A mammoth task lies before him and he'' needs all your help to free Uncle Scooby and Shaggy from the clutches of the evil Baron. © Hanna-Barbera Productions Inc. 1991
