Toto World 3 (토토월드 3), is an unlicensed platform game developed by Open Corp, released only in South Korea. A localised Sega Game Gear version for the US, titled Cave Dude was set for release by Innovation having appeared at Winter CES 1993, but despite copies being sent to the press for review, was cancelled for unknown reasons.

The game steals much of its graphics from other games, namely Super Mario Bros. 2 and Super Mario World. Some enemies resemble Tiki from The New Zealand Story.
