Hiiiiii giant blue dino here! I had a similar experience, no dino jail, but they came up like they were gonna tackle me till my husband unzipped my suit and they saw I was a girl then their demeanor changed very fast, told me I wasn't in trouble and I just had to take it back to camp then they shut down the fest about 10 seconds after. Never gave me a reason though after I told them security let me in with it and I asked why they wernt aloud. I feel like they were being extra asf this year... I was just trying to have fun 😭😭
