Baja Bill is one hungry dude. He's part of an exploration team that has discovered the ruins of an ancient civilization.
Tired and hungry from a day of hacking through the jungle, he climbs into his sleeping bag under a palm tree near the giant stone steps that lead up to the main temple in the ruins. In his dreams, the temple turns into a bonanza of Taco Bell® food delights. He races from room to room through the temple gobbling up as much Taco Bell® food as he can. But there's a catch. Hiding in the nooks and crannies of the temple are poisonous jungle cobras and scorpions.
Just when you least expect it, they jump out and take a bite! Cover them with Hot Sauce and they're goners. But if you don't move quickly, they'll give you a nasty bite. HINT: Look for hidden keys, crowbars, and a secret door to reveal hidden passages.
You can also jump into the water and swim underneath it for added adventure.
