Lost friendly guinea pig named Oreo with a small white chest patch near The Thumb Park during a picnic.

I lost my guinea pig named Oreo while I was walking in The Thumb park. She somehow slipped out of her carrier on the way to our picnic. Oreo is very friendly and has a distinctive small white patch on her chest. If anyone has seen her or spotted a lone guinea pig wandering around, please let me know. I'm really worried about her!
