Identifying Pet Help

[Ar1emis]

Hi! Currently in the process of reorganizing all my pets and stumbled upon one pet I had adopted through the pound. I checked the dates, and can't seem to find it in the archives. Here's the little guy here:

Pet's name: Bolts
Adopt virtual pets at Chicken Smoothie!

I'm assuming it's from an event since it's dressed up? Date adopted is 2016-03-04, Please lmk if you're able to find it!

Hey! This guy is from February of 2016. I hope this helps!

Not an event pet, but it's from February 2016 "Once upon a time" dog litter. All outcomes are similar to this (they're also dressed up. The rare mermaid dog also comes from this litter!)
