"The Loud House & Casagrandes Hangin' at Home Special" is an off-season half hour special. It is said to be the first crossover of The Loud House and The Casagrandes.
On a stay-at-home video chat, Lincoln and Ronnie Anne cover everything from fashion fails to fave TV shows; featuring new footage, classic scenes from The Loud House and The Casagrandes, and even a big surprise from Ronnie Anne.
This special was created in light of the 2019-20 coronavirus pandemic, hence the staying-at-home aspect of the special mirroring the people sheltering at home under quarantine.
As a result, this special isn't part of any season.
