From the Super Mario Wiki
Chuckola Cola is a popular drink found in Chucklehuck Woods from Mario & Luigi: Superstar Saga. There is another rare variety called Chuckola Reserve, which is needed to cure Queen Bean. It later appeared in Paper Mario: The Thousand-Year Door as Admiral Bobbery's last request; to get the Chuckola Cola Mario must give Flavio, the picky editor of Foppish Gourmet Weekly, a Coconut. After drinking it, Bobbery will join Mario's party. Also, Podley sells Chuckola Cola in Podley's Place, but it cannot be bought.
There are some appearance inconsistencies with Chuckola Cola between Mario and Luigi: Superstar Saga and Paper Mario: The Thousand-Year Door. Although actual bottles of Chuckola Cola were seen very rarely in Mario and Luigi: Superstar Saga, several were seen in the S.S. Chuckola, an ancient boat bound to ship Chuckola Cola across the world. Perhaps coincidentally, the Chuckola Cola was bottled similarly in both games, but it was colored differently: the Mario & Luigi variant was blue (but known to be red when seen en masse) and had a pink label while the Paper Mario: The Thousand-Year Door cola was purple with a yellow label.
Brewing Chuckola Cola
The entrance of Chateau de Chucklehuck has four statues, each giving four different steps to brewing Chuckola Cola. These are the four different steps:
||The main ingredient of Chuckola Cola is Chuckola Fruit, which grows only in Chucklehuck Woods.
||Place one Chuckola Fruit in a barrel that's been filled to the brim with savory syrup.
||Tell funny jokes to the fruit until it laughs, releasing soda bubbles deep within the brew.
||Bear in mind that the quality of both the fruit and the jokes will affect the brewing process.

Vintage Viola (PM2)
- Chuckola Cola (as well as Chuckola Fruit) is given a cameo appearance in Mario & Luigi: Partners in Time, where it appeared alongside Prince Peasley on a poster in Princess Peach's Castle's Shroom Shop.
- The beverage's name is likely a play on the popular soft drink Coca-Cola.
- In Japanese versions, the beverage is red and is known as Vintage Red. It is likely changed so it resembles less as wine. Bobbery's last wish was much more poignant in the Japanese version: scarlet wine in memory of Scarlette.
