Hey.
First off, welcome to the forums.
Secondly, there is a sticky at the top of this page that is where people post that they are going to abandon their pet. They generally tell you the name, stats and show you an image of it (e.g. Purple Grundo, Island Kacheek, etc.) It's really good if you're looking to adopt a pet. I got my Island Uni from there, as well as my Starry Ixi.
Here is the link to the thread, as it'll save you having to wait for GC to load.
Have a great time here at the forums!
