That is a past Monthly Collectable called Wild Thing, from the Thank You letter from November 2007. The letter and collectable are only available in the Marketplace or Exchange fourm now, as the item was only around for the month of November.
As for your other questions;
1. When your in a fourm, a banner should just be under the Gaia bar (you know, the one that say "Home" My Gaia" ect.). Click on it to go to the prom.
2. To have fun? You can talk in the prom area, just like you can in towns.
