When you go inside the temple of the ocean king, if you are not on a safe zone, it prevents you from getting hurt by the ground. But there is a certain time till it wears off.
I had the same issue. Just keep drawing it. It will come eventually...
If by "glass" you mean the hourglass from Phantom Hourglass, you can't draw an actual hourglass, you need to draw an Arabic numeral eight. (like this: 8) If you draw the figure with one circle on top of a smaller circle, it won't work.
Tap the hourglass at the bottom of the screen, then draw the symbol in the area provided, it will not show up, but it will work.
The hourglass dolphin is called an hourglass dolphin because its black and white markings resemble an hourglass!
An hourglass was used as a timer, with the size of the hourglass determining the length of time it measured.
There should be a button on the bottom screen. Touch it, and you should be able to use the crane.
go to the shipyard next to the deck on mercay island to customize.
phantom hourglass is released in 2007.
