Probably not, considering there’s still Ninjago and Monkie Kid

Maybe as a reference in another set but as for the theme itself returning, doubtful

Doubt they have a problem with another original theme, but It didn’t sell very well.

Sadly no. it's extra sad for me because my first set was from chima

A lot of their original themes haven't been received well/sold well, like Nexo Knights, Chima, Vidiyo, etc.

Even worse when they're app-based

I wouldnt say so

No
