Giga Pets Komputer Koala sleep times?

I'm a new Giga Pet owner, so I'm a bit vague on how the sleeping technique works.

I let him sleep for a while cuz he was acting cranky (Until 8:30 PM), but now it's late (9:08 PM), and I shut the lights off at 9:00 PM once again. Will he wake up when I turn the lights back on in the morning or will he wake up during the night wanting something as his stats drop during sleep?

I don't want to get up during the night to find out that my Koala wakes me up every second...

EDIT: He woke up after a few minutes of sleep, now I'm scared he'll do it again when it gets late and he's still not asleep.

EDIT 2: I may have screwed up its sleep time. Cuz it started wanting to sleep at 8:25 PM, but then I turned on the lights seeing if it only needed a nap and now it will only sleep for a few minutes now after that happened.

EDIT 3: Tried making it sleep again at 10 PM...it seems to be sleeping longer.

Granted this is a completely different version, but I put my Yoda to bed a little after 9 pm each night and he wakes next morning at exactly 7 am. The interesting thing about Gigas is that you can put them to bed whenever you like. In one of the first weeks I had my Yoda he stayed up with me until 12 am! Take my advice with a grain of salt however, I'm not familiar with the Komputer Koala and I'm just going by my experiences with Gigas.

I guess I chose to put my Koala to bed at 10 PM and he woke up exactly at 7 AM. Welp, that's his sleep schedule for now XD And my Koala is also a Wave 2 :3

in this guide, it states it goes to bed whenever you turn off the light and it'll have naps throughout the day.

That's all the info I could find, sorry I couldn't help more.
