They should all rush the skeletons and smash them into pieces and steal their daggers. Then quickly run into the cave to avoid the title wave that will wipe out the rest of the dangers. At about this time the cyclops will have probably made it down to them but they can easily distract and ambush the creature and slash his achilies tendons which will destroy his ability to stand and make him inevitably bleed out. By this time the only threats that remain should only be the giant hermit crab and baboon. Both of which are too big to enter the cave. It's at this time that you wait for them to sleep so that you can gather food and live. Looking daily for a plane or ship to signal with a large fire. At which point the rescue should be able to call in military support to take out the beasts and the sharks should also not be a problem since a helicopter should be able to land on the beach. Thus being able to air lift them all to safety.
best bet it to make a charge for the tomb the skeletons came out of. There are only 2 of them and skeletons will just fall to peaces when he hits them with the club and they can wait out the tsunami in there as it washes away all the other dangers of the island.
Thanks for considering the whole scenario, do you play too many console games? I think you're right here, the cave would be the safest. I don't know if that tiger will jump out of the bush though, and if the cyclops will crawl down. Also, you would have to carefully dodge the laser from the other-dimensional warriors. You wouldn't wanna be player 4 though, he's about to have a tough time with the cannibals, and with only 1/4 left of his HP, yikes.
I never thought about that, I guess they do. The style of Adventure Time has been inspired by a lot of modern illustrators, and a lot of modern illustrators have been inspired by AT, so I guess it's hard to avoid at some points)
