Froggers Adventures: Temple of the Frog Hints for Gameboy Advance
On the final boss of the game he is going to pit three of the elements against you. Fire, Water, and Air. Although it is easy I suggest having a lot of lives so that you don't have to restart the entire last level. In the Fire level you have to dodge fireballs and get the 5 coins. In the eater level you have to dodge ice shards and get the 5 coins. In the air level you have to run away from the flipping panels.
You need to gather coins because at the end of the game at the temple of the frog you will need 50 coins to get in and if you don't have it you will have to collect the coins then.
