First player, giving the correct answer will get a price.

11 Butterfly wolves - 1 is from 2009 (orange and yellow on the left), one is a 2018(orange on the right), the halloween one *broom) is 2016(?), the christmas one is 2014, the black dragon one is 2016, and the blue one on the left in front is 2009? those are the only ones i can think off the top of my head
