I didn't say the jungle was 100 meters tall, I said the tower is ;)
Let's say for funsies the water is shark-infested :3

That's what I mean. Since I doubt the the jungle is 100-meters tall, he should be able to see the tower.

Oh! Gotcha. Yeah, the answer is "look up". :3

No fair, MMM, you're a sharp one!

How about this, I like this one but people figure it out too quickly:

A man with nothing on him but a backpack is found dead in the desert, face-down in the sand. There are no footprints around him, nor any visible signs of murder or anything having been done to him. He did not die of starvation or dehydration. How, then, did he die?

parachute failed to deploy?

See that's what I'm saying, it sounds like it should be "omg what a mystery" but everyone gets it right away XD

I'll go play Professor Layton or something and come back later with some good'uns. :3

Oh I see that Riddles are going so fast but I see that I'm late ,waiting for other riddles
