The Witch's Cauldron (1984)

The Witch's Cauldron is a text adventure with graphics where the protagonist is turned into a slimy toad by the witch Hazel, apparently inspired by the classic fairy tale The Frog King. Imprisoned on the witch's island, the player needs to get the main character back to his original form by collecting ingredients and mixing them into the cauldron, with complementary adventure game puzzles.
