From what I can tell, this book came out at least in 2023, as judged by the oldest official video about it I could find on Youtube and the fact I found out that the LeapStart came out in 2016, not to mention Bluey debuting in 2018 and its popularity rising by circa 2021 thanks to Disney IIRC
Startup only. Also I downsized the video to match the original console's resolution.
I've released over the last 2 years 9 interconnected Loud House fanfics on r/theloudhouse, so instead of crossposting them here and flood this sub due to its lack of popularity I decided to dump all of them in this single post including their original synopsis and their release dates. And I'll also link their original posts via their own titles due to their inclusion of fun facts and references:
Ever wondered what if Lincoln had his own bi-generated self? Well too bad! Because in this fanfic, Lincoln bi-generates thanks to Lisa's drink she made, which leads to his second incarnation, Linka Loud, to exist. Linka even wonders the world as the Second Lincoln, from going to the school, to having a friendly bond with Stella Zhau, to even facing an unexpected enemy... Wait what?
After Lana and Lola cause trouble in Lincoln and Linka's Tardis, they accidently travel back in time without them knowing. Untill, of course, they find out.
The Heeler family from a different Earth are visiting the Loud house, only to have some issues with Lisa's newest invention, the psychograft, and the process of having someone take over someone else's body by using it.
Lori wants to take a break from the chaos by being on a different Earth only to encounter 3 new friends from that foreign animal kingdom, Bambi, Thumper and Flower, who wants to visit Lori's home planet and time.
After knowing how Lincoln and his bi-generated twin Linka bond, Lola decides to find a way to bi-generate without anyone knowing so she can have the perfect sibling. However, the new Lola she will meet will not be like she expected...
After hanging out in the Heeler household, Lincoln and Linka, alongside a few more, decide to explore a world featuring 3 talking bears and their magical box.
An alternate version of Lori decides to visit the Loud family and finds out about Linka's goal if finding the Tenth Doctor. It is now up to her, the original Loud family and a few more friends to track him down, only to stumble across something so dangerous they have no choice but to help him out.
The Louds, Bluey and Bingo accidently crash in Wuzzleburg after a huge mishap, only for Linka to find someone to date with. Until their Tardis gets fixed, it is up to Lincoln to stop his sisters from ruining Linka's date once and for all.
Lana and Wubbzy mess around with some infostamps, only to accidently brainwash Wubbzy's own clone into thinking he's Kara. It is up to Lana and Wubbzy to find the clone and restore his memories back becuase anything worse could happen.
