[Right! Mumble repeats it with a nod. Just to cement it in his brain.]

It does look a little boring around here. I mean, there's no sky, and everything's so...beige. [He looks over at the colours Discord has prepared.] But I don't think I've seen anything that bright before.

[Has he even seen the colour green until this day? Let's not think about it.]

Do you need any help? I'm feeling...spon-tan-you-ous.
