From All Time Low To the creator of Lollapalooza Perry Farrell, this Bert doll has been spotted with quite the names at the 4 day Chicago music festival. The best part is he has his own instagram account and posting this journey every step of the way! He's garnished some pretty cool pictures but it's his instagram story that makes it so comical. Not quite sure where Ernie is but Bert is definitely having the time of his life. To get in on his adventure follow him @bertatlolla. You never know where he's going to pop up and who he's going to pop up with!
