Worm comes after you get the dumpster dive: do the trick to go underground. Follow the worm and bat it's bombs back at it. The monkey comes after you get the glider. Move up and down and bat the nearby bombs and it's bananas back at it. I don't know about the worm, but you may ahve to fight the monkey several times; fortunaately, it doesn't heal between fights. Groupies will get you more cash per trip; you lose all groupies if you crash, so don't get them until you have a good routine down. I did the 50k badge like Bojak said: grab 3 groupies, do tricks all the way up, do tricks all the way down, try to get as many pole vaults as you can, and if the vault is high/long enough, try to get a jump (up up up) in there. Good luck!

it would be an awesome multiplayer if you went against real people with loads more armor and weapons and got xp (Experience points) from kills and completing missions. every time you level up to a new rank that can buy better weapons, get more gold from fights and upgrade your character with skill points. If you thinl this would be an awesome idea hit the + sign.
