There are lots of qualities that need to be fulfilled in order to be a member of the Sand Bandits. One of the most important quality is to not be selfish. Sand Bandits steal expensive items from the queen, but it's not for us; it's for the people of [map 260000000].

A selfish individual will not be able to control his or her desires and lay hands on those items. A member of the Sand Bandits should never, ever do that. This is why the next test will involve your level of selfishness.

It's simple, actually. All you have to do is donate 10,000 mesos. Too much? Well, but if we're to rescue [map 260000000] from the queen, we'll need much more money than that. If you can selflessly donate your 10,000 mesos, then I'll believe in you.

You've done very well so far. Don't stop now... but then again, it's hard not to be selfish with mesos...

You are donating 10,000 mesos. I am sure you have lots of things to buy with that money... and yet you've decided to donate it for the good people here at [map 260000000]. That's very commendable...

You have now passed all the tests that I, Sejan, can offer. That doesn't mean you are now a member of the Sand Bandits. There are other hidden members of the Sand Bandits around town, and you'll have to be accepted by all of them to become one. Keep working.

That's not enough. 10,000 mesos aren't hard to get, as long as you don't rush yourself and keep hunting.
