On all Carnival cruises, one day they will serve the drink of the day in a coconut which has been carved out and has a carved face of a monkey on it. This are affectionately known as Monkeyheads. There is a loyal CCL group who like to waste money on cruises and these drinks and are known as the coconut monkeyhead wasters group. You can join also, it is just a fun thing. The monkeyheads are about 15.00 each so you see the waste. there is a cup inside that holds the drink. refills are the same price as any other drink. you can read about the MHWC on these boards under user groups. There is even a group cruise planned for next January so all of us can meet and greet. The only requirement to join is a decision to waste money on drinks and cruises, and not complain.
