Tom is married to Shiv, but Greg is his real partner on the show. (When I asked costume designer Michelle Matland about pulling everyone’s looks, she said Tom’s suit was selected to complement Greg’s clothing, not Shiv’s.) 

Activity found on the official Japanese site for WarioWare, Inc.: Mega Party Games in 2003, whereby the user's mouse becomes a space heater and a group of cats follow it around a white void.

Officially licensed Boo T-shirt from Japan, featuring the slightly grammatically incorrect English caption "TERESA [Japanese name for Boo] IS IN HAUNTED HOUSE / ALWAYS FLOATING".

In Super Mario 64 DS, if Wario dives into a pillar in Shifting Sand Land at a specific angle, he will be transported below the course.

However, since he is also below the death barrier, he will not die immediately. Instead, he will spend a long time falling before encountering a failsafe far below the regular death barrier, at which point he will finally die.

Officially licensed plush of Yoshi with a Fruit, from Japan. While these fruits were known as "apples" or "berries" in the past, the current official name used by Nintendo currently is simply "Fruit", leaving its nature purposely ambiguous.

In Super Mario 64, normally, all enemies patrol their respective areas and during regular gameplay, it is rare to see Bob-ombs crossing paths with other enemies. Whenever it happens, it reveals that they are set to explode when any other enemy is near, even if their fuse is not lit and they are merely walking around.

A shell-less Koopa Troopa will run around completely randomly if left alone, and by observing it for a long enough time, it will eventually run into a patrolling Bob-omb, dying as shown in the footage.

Super Donkey Kong '99 is an unauthorized 1999 Donkey Kong platformer for the Sega Genesis based on Donkey Kong Country. While most versions of this game feature a single ending screen with Donkey Kong and Diddy Kong standing on a flat plane in the darkness, a later release adds an animated ending where the two are shown to have a brief conversation in broken English.

Officially licensed 1995 Donkey Kong keychain from Japan.

French Mario plush of dubious legality. While appearing so off-model as to suggest it is unauthorized, some units are found with tags that imply that it was a result of an obscure licensing agreement.

"Yoshi Demo" was an early tech demo for the Game Boy Advance, developed far before its public release, consisting of a very rough port of the Yoshi's Story engine from the Nintendo 64 to the new system.

One of the graphics included in the demo was this particularly frightening-looking Bullet Bill with uncharacteristic fangs and glowing eyes.
