Uranus
A planet rotates on its axis, an imaginary line that runs from its North Pole to its South Pole. This rotation determines the length of a day on the planet.
Pretty much every planet has an axis, because an axis is what a planet rotates around. Any planet that rotates has an axis, and pretty much every planet known rotates.
Uranus is the planet that spins on quite a significant tilt which makes its axis almost horizontal compared to its orbit around the Sun. This unique characteristic gives it extreme seasons where each pole faces the Sun for about 42 years at a time, causing dramatic temperature changes.
"Horizontal" isn't really the correct "scientific" way to describe it, but the answer is Uranus.
Neptune rotates horizontally on its axis, like most other planets in our solar system. Its axis is tilted at about 28.32 degrees relative to the plane of its orbit around the Sun, causing it to have seasons similar to Earth.

Uranus
A planet rotates on its axis a point which travels through the north and the south of the planet. On earth the axis is found at the north and south pole of the earth.
The Earth rotates on its axis, which creates day and night as different parts of the planet face the sun.
Mars
A planet's axis is an imaginary line that runs through its center, connecting the North and South Poles. The tilt of this axis is responsible for the changing seasons on the planet as it orbits the sun.
