Robu is a timid Paca. When they start talking about something they like, they'll get very energetic and loud, but for the most part they're soft and quiet. Their leafy body fluffs up when they're scared.
They have an aspiration to fly like the winged Paca, though as impossible as it may seem. They love watching the clouds, and they love rain. The night sky they aren't so fond of, since they can't see a thing, but they still find solace watching the stars every once in a while (though it's definitely better with a friend).
Frosch is their sibling and they love them very much! They like to keep Frosch updated on what they've been doing and all the new things they've encountered.
