Jay's inventions are said to fill entire warehouses, some of which he cannot remember the names or functions of. Some of his inventions are: A blanket that can keep you cold on warm nights. A parchment that can be written on or stretched into a waterproof tent. A device that cores apples off of the tree before they are picked. Extendable stilts. This invention apparently malfunctioned on its first use, repeatedly bouncing Jay up and down between six feet and sixty feet. After a hundred bounces in the span of two minutes, Jay was dizzy for a month.
