Sesame Street: Elmo's Letter Adventure and Number Journey are kind of like Pokémon, in that they're kind of the same game and act as counterparts to each other, but completely different in literally every other aspect and this was a bad example. Basically, they're the exact same game, but one teaches kids about the alphabet and the other teaches them about numbers. Got that? Good, here's some hidden and debug content.

Unused Graphics

The Elmo's Playroom sign from the PlayStation version is hidden in the main hub.

Unused Music

00000000 002F9B60

To do: Ripped with N64 SoundBank Tool, which might be inaccurate. If possible, try getting it to play in-game to get a accurate audio rip.

An unknown music track can be found in the rom, this doesn't seem to be used anywhere in the game. It sounds similar to the track played after completing a level, just with different instruments.

Hub World Music

Because of a programming flaw in Letter Adventure, the hub world music doesn't play, despite the song being inside of the ROM. Number Journey would later fix the issue, and the music would play there.

Debug Display

Apply the below code to enable a simple debug display. This will show engine statistics and actor information.

Level Select

A debug level select option is present at memory location 0x800301C8 in Letter Adventure and 0x800327A4 in Number Journey. This doesn't work anymore as it has no controls to operate the menu.
