Gliese 436b / Classification: Hot Ice Planet / Features: Despite high temperatures exceeding 430°C, the planet's strong gravity holds water molecules so tightly they exist as ice—a mysterious planet / Personality: Restless

Its elliptical orbit is so extreme that at its furthest, it is three times the distance of Pluto / Moon: Has one moon named Dysnomia As more ice bodies similar to Eris were discovered in the Kuiper Belt, the need to clarify the definition of a planet arose.

Earth: Ugh, isn't there anything to do? Pluto: I'm... a dwarf? I'm a dwarf planet?! Sun: Sigh How many times is he going to do that? Every day it's 'dwarf, dwarf, dwarf.'
No!! My ocean is drying up. At this rate, I'll end up like Kepler-16b! T_T
