Shooting or walking into this ball will cause it to detach and roll off down the hill. In Vinewood Hills, there is a juice stand with a big orange ball attached to the top.This reference is further expanded upon by the player spawning in front of the mural after the completion of Last Dose 5 - BDKD and, sometimes, after completion of Liquid Assets. In the Los Santos Drug Wars update, Dax references this mural in the mission First Dose 1 - Welcome to the Troupe, asking the player if they 'Know anything about the eggs on Mount Chiliad?'.

On another mural, Bigfoot and the number 27 appear, referencing that in story mode the player needs to collect all 27 regular peyote plants before the golden ones can appear, which allow the player to transform into Bigfoot.

This mysterious mural can be seen on the artwork inside of the Mount Chiliad Launch Facility.

Although the flying UFO on top of the mountain cannot be seen in GTA Online, as it is exclusive to story mode, symbols relating to this mural, instructing the player how to see the UFO, can be seen under Mount Chiliad's observation platform, on the side of the mountain, at the Beam Me Up site, at a small silo in Grand Senora Desert, and at the Altruist Camp.

The UFO and Alien Egg were featured in a Bunker Resupply mission, and the jetpack was added in the Doomsday Heist Update as the Thruster. This was later revealed to reference a singleplayer dlc that was scrapped and somewhat reused for GTA Online.

A mysterious mural inside the tramway station atop Mount Chiliad includes a drawing of what appears to be a jetpack, a UFO, and an Alien Egg.

Investigating online reveals that the ghost is Jock Cranley's wife, Jolene Cranley-Evans. During the time the ghost is present, the word 'JOCK' appears written in blood on the rocks under the ghost. The ghost fades away if the player gets too close, and reappears when the player moves away. The ghost doesn't move, and will not react to the player being present or shooting it.
