Balloon Trip (lost Nintendo DS tech demo; 2004)
At E3 2004, Nintendo showcased several tech demos for their new handheld console, the Nintendo DS. One of these took inspiration from the 1995 Super Nintendo Entertainment System game Super Mario World 2: Yoshi's Island. It was titled Balloon Trip, named after the mode from the 1985 Nintendo Entertainment System game Balloon Fight.
In this demo, Baby Mario is being carried by the Stork until Kamek knocks him away. Baby Mario drift toward the ground, kept aloft by three balloons. Touching an enemy pops a balloon, and if all three balloons are popped, Baby Mario is abducted by Kamek. The stylus is used to draw clouds that direct Baby Mario and to draw circles around enemies, turning them into coins. The goal of the game is to collect as many coins as possible to achieve a high score. If Baby Mario makes it to the ground, Yoshi will catch him and the player will be congratulated.
