The A Friendly game of Leap Smurf achievement is worth 30G and is unlocked by freeing The Cursed Frog without getting hit.

This is the boss fight at the end of the Enchanted Forrest. This isn't a hard fight once you get used to the attack pattern, which is the same every time for this fight. There are three phases to this fight:

Using Clumsy is recommended because his tumble skill is very helpful.

1. Bubble, Bubble + Tongue, Jump, Jump
2. Bubble, Bubble, Bubble, Bubble, Bubble, Tongue, Jump, Jump, Jump
3. Bubble, Bubble, Bubble, Bubble, Bubble, Bubble, Tongue, Tongue, Tongue, Jump, Jump, Jump, Jump

When the Cursed Frog uses the bubbles you will want to jump over them to dodge. Same thing goes for his tongue attack which is a reach attack that stretches across the entire screen. Once he is done with the tongue attack he will start to jump. Simply dodge them until you are indicated to hit the Frog.
