The game was made in April 2003 to coincide with the first long-form season of Oobi. It was part of a series of four matching games, the others being Rhyme, Letters, and Numbers. These four games were meant to teach basic retention skills. The earlier games from 2002 were simpler and didn't have much educational value.
"Give Oobi a hand in this remembering game. Oobi displays three items for you to remember (for example, a hat, shirt and mittens). One is removed and replaced with a question mark. Below, Oobi offers two choices: one, the original item in the initial set, and the other, an incorrect or extraneous object. You must then remember which item was in the original set and click on the missing item. If the correct item is clicked, you win a star. If the incorrect one is clicked, Oobi tells you 'uh-uh.' Finish the game by winning all three stars!"
All of Oobi's sprites are recycled from earlier games.
