Child of Big Bob-omb

The Child of Big Bob-Omb, sometimes referred to as Prince Bob-omb by the community, is a supposed character in Super Mario 64 and the son of Big Bob-omb. Despite being not recognised officially, many have recounted seeing the Child of Big Bob-omb in their game. The Child of Big Bob-omb has the appearance of a regular Bob-omb, except slightly smaller and wearing an oversized crown reminiscent of their father's.

Behavior
Much like the White-eyed Chomp, the appearance of the Child of Big Bob-omb is an indicator that the player's copy of Super Mario 64 is set to have heavy amounts of personalisation. Although many never see the Child of Big Bob-omb due to the happenstance of where they appear. On the last star of Bob-omb Battlefield, Behind Chain Chomp's Gate, he can be found atop the mountain where Big Bob-omb once resided. He can be interacted with, where he declares that he will right the wrongs of the king.

For the few that have seen the Child of Big Bob-omb, they go on to claim that he can be found within Princess Peach's Castle later on. Specifically, he can be found upon the second floor where he will run from Mario. No matter how fast Mario goes, he isn't able to keep up with the Child of Big Bob-omb. If chased for long enough, Prince Bob-omb will flee into the Bob-omb painting on the second floor, where Mario cannot follow since it's not an enterable painting.

Those that left the Child of Big Bob-omb alone on the second floor however were able to see them walk away. If the player slowly follows the Child of Big Bob-omb now, they will not flee. The Child of Big Bob-omb would then jump into the Bob-omb painting again, although now Mario can follow with them and enter a brand new location. What this location is exactly is unknown, although many presume it to be Bob-omb Village.

Legacy
The Child of Big Bob-omb has yet to reappear in the Mario franchise, not even reappearing in Super Mario 64 DS. His absence is unexplained, although it's likely that he was a rejected character idea for Super Mario 64, and his remnants were repurposed and reused by Nintendo's experimental A.I..

Trivia

 * A statue of a Bob-omb with a crown can supposedly be found within Bob-omb Village. It's reasonable to assume this statue is dedicated to Prince Bob-omb himself.
