Malu and I get to Olmec and die again a couple of times, get cursed, find a leprechaun, a rainbow, and a pot of gold, before I finally manage to use 4 bombs to get through the floor in the Olmec arena, and exit.
I encountered the second form of Olmec, who promptly bombed me out of existence. I believe we have to destroy this form to open up another world. But the good news is that we ended up delivering a mount to Mama Tunnel, and we now have tunnel access to World 4.
We got the $50,000 for Mama Tunnel. Next one is the hired hand. Also we figured out to dig down to the Egypt level, which is an evolution of the temple levels from the first game, with new enemies, including cat mummies.
We're trying to get a helping hand for Mama Tunnel. This is very difficult, since the helping hands are very suicidal. We have tested with Atlas from 1-4, and have learned that the one who releases from his coffin is the only one who can pick him up, and he will stay with this person. In This allows the second player to stay safe with Atlas, and the party leader to run through the levels alone. But for this strategy to work, we have to run through worlds 2-4 with him. Maybe it's easier to start in world 3 and hope for a hired hand shop?
A helpful fact we discovered: Pets can cure poison by licking you.
Helpful facts from the Giant Bombcast: You can rope onto spikes without getting damaged. Also, apparently, there is a secret castle level hidden in the jungle, you can bomb down in a level that doesn't end vertically where the exit is.
