Do We Have This One?? This is when a character is inside some variety of gem. Often this implies that the escape will be by being released, (ie. the owner of the gem would magically dissipate it or something) rather than by shattering of the gem, but shattering is not ruled out either. Examples include, aside from the Star Fox Adventures one in the tentative page image, princess Zelda being imprisoned in a crystal towards the end of Ocarina of Time. Link being transported out of dungeons by being encased on crystals might qualify as a milder example, though he is only VERY temporarily trapped in a VERY loose sense of the word.
