Mamma Gingertree - one of the first characters on the board (she replaces "Plumpy" from some of the older editions)
Mr. Mint - a lovable guy who loves peppermint, who lives in Peppermint Forest
Grandma Nut (also spelled Gramma Nut) - who loves peanut brittle, and lives in Peanut Acres
Lord Licorice - who, you guessed it, loves licorice (in the movie version he is the villain), and lives in the Licorice Forest
Jolly - the gumdrop animal who lives on Gumdrop Mountain
Gloppy - he is the Chocolate (in earlier versions Molasses) monster -- you don't want to get caught in his swamp, or you lose a turn
Queen Frostine - she is an ice skater, and in the movie version is changed into Princess Frostine
Princess Lolly - who loves lollipops, and lives in Lollipop Woods
I learned the most about these characters from watching (many times) the Candyland animated movie that came out a couple of years ago. My kids love it, and the older ones have also found the game more enjoyable to play with the little ones after watching the movie.
The Candyland characters are such an endearing part of many people's childhood.
I have seen a couple of birthday cakes decorated with a Candyland theme, which I always think are very cute.
Check out this video below which shows the making of a Candyland Birthday Cake in one minute. Very cool!
