Trying to figure out what flavor the McDonaldland meal's shake is supposed to be?

I take it it's not strawberry.

Grinch meals are available at Mickey D's. You can get a Big Mac meal or McNugget meal and you can have some special Grinch Salt that'll make your fries taste like green dill pickles. Usually at McDonald's you can get a Happy Meal prize or a collectors' glass, but this time, you get a pair of socks. Very nice, fun socks I might add. But the weird thing is, the cost of the Grinch Meal is crazy expensive! Our three meals cost like $15 each. Insane! 

Your reactions, please. And Merry Grinchmas!
