The timeline:

Meet the next gen Disaster Twins: Diamond Blue and Royal Blue! (4) They’re both from an alternative timeline where young adult Minty Blue decides to sneak into an abandoned factory and ends up discovering two freshly mutated hatchings lying near a damaged pipe, who he eventually adpots as his own. While Martha was rightfully furious at her son for sneaking into places he shouldn't be, she eventually gets over it and accepts her role as "Gran-Gran".

Diamond Blue is super optimistic and outgoing, while his sister Royal is more asocial and extremely timid. They get along with their grandmother really well and even learn how Minty Blue became a part of her life.

Minty Blue still uses the internet, although the twins don’t understand it just yet. Nevertheless, they support his passion and never really question the fourth wall breaks.
