FrogAA is a free browser MMO game about getting to the top of the swamp. You adopt a frog, train it, and spend the rest of your time proving it against other players, with nothing to download or install and a world that keeps running even when you are not logged in.
Frog Adoption Agency was submitted to SlowDen by Croaksworth. SlowDen did not make this game - it is published here from the developer's own submission, added on 2026-09-21. It runs in the browser with no download, no install and no sign-up.
