To be honest, it' hard to choose between Yeti, Nutcracker and Tiffi (seriously, I love three of them so much. )
Yeti because I love how he uses his power so to crush candies and I found him as a very funny character.
Nutcracker because he is cool and I really love his determination to help everyone around and his power when he toot his trumpet...seriously, that makes him a very cute character (plus I love his two costumes Prince of Diamonds and King of Hearts too. )
And about Tiffi, she is amazing on her own. I like it when you have 5 moves left in a level and Tiffi claps her hands. It seems that she wants to cheer you up so to complete that level even if you have only 5 moves left. It seems that Tiffi believes in you so that' s why I loved her (even and her cry after loosing a level makes her so adorable. Poor her... ) .Oh and I love her Astronaut outfit too. It makes her so cool.
As I said, I love these three characters so it's hard to choose between them.
