Our Sun is overrated.~Australian Ranger
Because Yynglea has 2 suns, there’s always day on the planet. This is why most of the creatures draw their energy from the suns and they don’t need to sleep.
The Mlams, a race of Yyngleans, are 3-meter tall gentle creatures that just learned to produce simple tools. They were also foolish enough to share their weaknesses with the Hoppers.
