During Hunt for Red Raktuber, Larry is taken away forcibly to the motherland by Pescaling Pax. Pescaling then abandons the player on a deserted island. This is the island where the player first encounters Chuck, poorly disguised as a palm tree. After Chuck is spotted and told about his ineptitude at disguises, he remarks Hmmm... We may need to have a meeting about that. To escape the island, Chuck allows the player to ride on his belly to East Ardougne.

On 10 August2010, as a hidden update, Chuck was given a second right-click option "Hide-n-seek"; however, the option was moot, as it required a player to be standing next to him for it to work (something not possible, as Chuck is locked in a polar bear pen). The problem was fixed approximately two weeks after its release.
When claiming a reward from the Penguin Hide-n-seek Distraction and Diversion one of the chat options says "Show me the money!" This may be a reference to the movie Jerry Maguire.
Also, when the mouse is hovered over Chuck, a player can see the left-click option "Talk to Chuck." When paired with the option in later dialogue "Show me the money!" this could be seen as a reference to the investment company Charles Schwab.
If you stand on the outside of the zoo fence nearest to Chuck you can still talk/exchange penguin points with him (useful for saving a few seconds walking to him from east bank/teleport location).
On 27 February2017 Chuck's hints for penguin locations started to include the ghost penguin. The clues however do not specify if a hint is for the ghost or a regular penguin.
