The bounty system doesn't just apply to one person, it applies to all people. However, there are ranks to keep things in order. The bounty's will vary depending on what rank said person is, the lowest being G, the highest being SS. The bounties will also work depending on what the person has done and how this has gained the attention of people. For example, if you've done a small task like say save kittens from trees, help out with skateboard fixing, and so on, then you'll be at Rank G with a possible bounty of only five to ten munny. Ranks don't determine the strength, but only one current person has the bounty of SS.
Rank G: 1 - 100 munny
Rank F: 100 - 300 munny
Rank D: 300 - 800 munny
Rank C: 800 - 1,500 munny
Rank B: 1,500 - 5,000 munny
Rank A: 5,000 munny - 10,000 munny
Rank S: 10,000 munny - 30,000 munny
Rank SS: 30,000 munny or higher
