Black, White & Pink All Over...

I think the riddle is suppose to be what's black & white and red all over... but today we have to use pink. I saw this small tree branch on the ground today and realized it was pink. After looking up some reasons for pink bark, it may have had some type of bark disease. I don't know for sure, but I thought it would be the blip today just because of the colors. It's hard to turn down pink.. haha
