Rotten Tomato was a grouchy and overripe tomato that lived in the Pun Garden on the Isle of Wonder for an unknown amount of time. Eventually, he was picked up by Alexander and briefly taken on his quest to rescue Cassima. Alexander attempted to obtain some swamp ooze, and inadvertantly became caught in an argument between Bump-on-a-Log and Stick-in-the-Mud. Feeling that the log might need some ammunition, the prince gave Rotten Tomato to him. Almost instantly, Bump-on-a-Log hurled the tomato into the swamp. In retaliation both Stick-in-the-Mud and Rotten Tomato began hurling swamp ooze at the log until all three parties were exhausted. Rotten Tomato has remained in the sludge near Stick-in-the-Mud since.
Rotten Tomato is a character and inventory item found in King's Quest VI: Heir Today Gone Tomorrow.
