Roomba and Pebble (Patreon)

Another of the october doodles that ended up being a little thing on its own, haa I always forget I want to do more monochrome pics more often, after all, multiple OCs fit the monochrome category too... Pebble specially! Maybe he's trying to replace Roomba-chan at her job hmm..?!
Which reminds me I never gave her a proper name.

Anyway, hope you have a good week !
