No planet is composed of mainly frozen water; Mars has probably the most frozen water of all the planets after the Earth.
However, older textbooks and teacher's notes may well refer to Pluto, which is now classed as only a "dwarf planet" and is composed of roughly 50-70 percent rock and 30-50 percent ice.
So, although Pluto has a lot of ice, it has more rock than ice (frozen water).
