The is an item in.

Location and Uses
The MM3D: is given to MM3D: by Jim, the leader of the Bombers Secret Society of Justice, after he completes their Hide-and-Seek test. The MM3D:, which can hold twenty entries, keeps track of the schedules of characters in need. Every time MM3D: makes a promise, a Promise Sticker is added to the MM3D:. If MM3D: solves a character's problem, he will receive a reward and a Happy Sticker will be added to the MM3D:. Once an entry is fully completed, a Happiness Seal is placed next to it. A picture of the character appears on the left column of the MM3D:, while its schedule appears in the adjacent row. Blue bars show when a notable event will occur.

In, the MM3D: is instead given to MM3D: by the Happy Mask Salesman, who says the MM3D: was most likely dropped by the Skull Kid. It includes entries for every character that gives MM3D: an item and for ongoing and rumored events. MM3D: can also set an alarm to a specific time so Tatl reminds him of any given event.

Promise Stickers
Promise Stickers are shaped like exclamation marks. They are added to the MM3D: each time MM3D: makes a promise or appointment, or each time he completes a significant event. Details regarding the promise or event are displayed when the sticker is highlighted. If MM3D: travels back in time after receiving a sticker, it will be grayed out until MM3D: makes the promise or completes the task again.

Happy Stickers
When MM3D: receives an item such as a MM3D: as a prize or as thanks, a ribbon-shaped sticker is added to the MM3D:. When he receives a MM3D:, a MM3D:-shaped sticker is added instead. Details regarding the item and the means by which it was earned are displayed when the sticker is highlighted.

Happiness Seal
When MM3D: completes all available objectives for a certain character, a Happiness Seal is added to that entry. This includes obtaining all previous Promise and Happy Stickers for that character as well.

Trivia
