I'm going to try and answer these ten at a time. There's too many for one post LOL
Q1. Who was the first OC you made a profile for on Toyhouse? Why them?
Listra is one of my oldest characters and closest to her final design. Her simple appearance and cheerful, accepting demeanor make her a good candidate as a mascot. She's one of my favorites right now.
Q2. How do your OCs feel about the internet? If it doesn't exist in their universe, how would they feel if it did? What kind of sites do/would they go on?
Most of my characters are fairly happy-go-lucky and comparable to average "let's just not look at the awful parts =D" Earth Internet-goers. The ones who would get upset at the porn of stuff would be calmed down by the various emotional- or healing-orientated Nice Person characters.
Q3. Which of your OCs sleeps the most? Who's the hardest to wake up, if it's not the same person?
Holly on both counts. She fulfills most of the tropes of the lazy girl. Rhubarb is also a contender.
Q4. Which of your OCs is the cleanest? Who takes the longest showers/baths, if it's not the same person?
Most of the girls take pretty good care of themselves, especially considering the medieval-esque setting of the world. Goldenfern is probably the cleanest and most well-kept of the girls, but she would hate to waste water; more self-indulgent showers or baths probably better fit Penelope, who's from a noble family and wouldn't really think about it.
Q5. Which of your OCs has the biggest sweet tooth?
That's easily Lilina. Yes, she even beats Rhubarb. Fortunately for her, not only is she a good baker but it all goes to her breasts.
Q6. Which of your OCs stays up the latest? Who gets the least sleep, if it's not the same person?
I haven't decided if the gods of my world need to sleep or not, at least the "people" ones. Arteline is the goddess of the moon (a literal night owl.)
Excluding those characters, I would probably name either Acacia (a clubber / DJ) or Holly (generally careless) as late night girls -- yes, I know I named Holly as the sleeper too, but she sleeps during the day 'cause she stayed up all night.
Q7. Which of your OCs is the most forgetful?
That'd be Locust, who is generally a sweet but very dumb guy. Yes, I do have male characters.
Q8. Do any of your OCs have notable dreams, or at least any recurring themes that appear in their dreams?
Thanks for reminding me about Aletheia, a blind seer. The real world she can hear and not see, but prophetic visions she can see and not hear. She can get these visions while sleeping, which will make them abstract and difficult to understand because they're mixing in with her dreams in strange ways.
Q9. Which of your OCs is the worst cook?
While I haven't really thought about this, I'm going to preemptively answer with Daisy, because I need something for her to be bad at.
Q10. Which of your OCs is the best cook?
As stated earlier, Lilina is a good baker. She learned from her mother Laeticia. Most of my characters are at least decent cooks with a specialty dish they're particularly good at.
