I loved playing on this website when I was a kid years ago, so that's why I decided to post this.
Nevaland was a selection of games on the CBBC website from 2009 until 2012 starring a bear named Nev, the website on the Wayback Archive no longer loads but I found a few games from the website.
Bandit Bites: Found Nev it Up: Found Nev's Jam Buster: Found Gumball: Found Aquapigs: Found Bath the Bear: Lost Quick on the Draw: Found (right-click on the Flash window and click 'Play') Rap it Up!: Found Ducky Bounce: Found Bear Pairs: Lost
BTW: The Geox TV Ad here has the same similar music as Gumball or maybe the same.
