Yes, even Yumalopes need sleep. Insomnia is a bitch. I suffered from it at one point myself. I was cranky and just unpleasant to be around. Can't remember what I did to solve it.
Anyways, Cocoa here is suffering the same. What's bothering her? WHo the heck knows, maybe she's been pranked one too many times and she daren't sleep. Maybe it's something completely different? All we can do is hope she's back to her bubbly self soon~
This great piece was done by my good friend  Zaezar back when his patreon had different rewards and incentives. Nowadays his patreon funds some of his stream activies. Lots of fun and you should check him out, he's funny and entertaining! www.twitch.tv/Zaezar
