Dragons only appear in the sky/snow area. But only when its unlocked. The panther is unlocked when you reach level 29, and only appears in the jungle area. Level 30 is the best, you unlock some cool cheats.
Just to clear things up - lol - this game is not stolen - it was my first version of flood runner which I discarded as a test and made Flood Runner 2 instead.

I only put the game here cos I had a lot of requests to do so.
Flood Runner 2 is better ;)
