Which fact about me is the lie?

[murusa.]

I'll give you three facts about me and you have to guess which one is the lie!
If I put a check mark on it, that means you're correct! If I put an X on it, that means you're wrong!

Aight, here are the facts:

1. When I was a baby, my grandma fed me so many blueberries that my ass turned blue.
   
2. I have 3 dogs and 1 cat.
   
3. I was on the skating rink when I was 5.
   

1 is so obviously the lie
