The best thing about this new costume is that it actually benefits you .. at least for a limited period of time. I wish the time wasn't limited and I wish they'd add more costumes that give you additional benefits beyond the regular friend's ability.
It works for me if I play a level with yeti available as a selection and use the new costume on yeti after I select him. Are you sure you're actually selecting yeti for the level and using the new costume?
I haven't earned him yet it was released when I was at the end of the road. But I really like stars only. With trying to do the levels released weekly, actually work and the champion of champions-special levels would be really hard to do in addition.
Wow, I have this costume ! But I'm have a bit sad because if it have the sound when yeti put wrapped candy, it will be better ( like whole costume of Yeti ).
9+ more days left to win Yeti's new tennis player costume! And, a new Dachs Delivery Service is running concurrently so your new stars can count in both events!
As you can see from the graphic below taken from my scrapbook, Yeti Tennis Player has only the power to add one wrapped Candy with every twelve cyan candies collected from the board. I am not sure where the idea of "double power" came from.
