Ronnie Anne & Sid Chang

Ronnie Anne Santiago and Sid Chang are best friends.

Origin
They first met in ''[https://theloudhouse.fandom.com/wiki/Friended!_with_the_Casagrandes Friended! With the Casagrandes]'' when Ronnie Anne ordered a hot dog, and later when she skateboarded over a fire hydrant. Having seen it, Sid offers to try it, but instead, ends up skateboards backward, heading toward a statue. Ronnie Anne comes to the rescue, throws a tether-ball to Sid, and she grabs it just in time. Concerned by the "performance," Ronnie Anne asks if Sid ever skateboarded. Sid claims she didn't, but she doesn't care because it seemed fun. She also claims that she moved into Great Lake City and wants to try everything she can. Ronnie Anne becomes fond of Sid, thus the beginning of a whole new friendship.

Sometime later, they met again outside the Casagrande building, as Sid's family is applying for Apartment 3A, which is directly above Ronnie Anne's apartment at 2A. The besties were thrilled they could be neighbors. But the chances of that are moderately low. According to the building manager, who's also Ronnie Anne's granddaughter, Rosa Casagrande, they'll be more potential tenants applying for the apartment, leaving it up to the owner, Mr. Scully, to decide. Aware of this, Ronnie takes matters into her own hands, with help from her brother and cousins.

The plan: Carlota and Ronnie Anne went around town to take down fliers for the apartment, Bobby and Carl kept any potential tenants away, and CJ kept Abuela distracted. It all goes well, forcing Rosa to have Mr. Scully give the apartment to the Changs since they were the only family who applied. But just as she was about to call him, he calls her, asking her to show the apartment to his friends, the Reynolds, much to Ronnie Anne's dismay.

The kids were disappointed that the Changs won't get picked, but Ronnie Anne, unwilling to give up, come up with a new plan: sabotage. While Abuela's distracted, she can make the apartment look messy (with help from her new best friend), and besides, she can show it to Reynolds so that they won't want it. After the "messy" apartment was ready, Rosa offered to let Ronnie Anne show the apartment to the Reynolds so she can take care of Carl, who reluctantly pretends to be sick.

Once Ronnie Anne showed the apartment to the Reynolds, they were not pleased at all. As if the massive mass was bad enough, they also heard clog dancing from upstairs, which was CJ perform for Ms. Kernicky. In addition, Bobby dumped trash on the street, and the windows were glued open, allowing birds to fly in. Having Seen enough, the Reynolds left with their minds made up.

Just when the plan went well perfectly, it had one downside. After seeing what a pigsty the apartment was, the Reynolds told Mr. Scully all about it, and he pinned on Rosa, since she was supposed to take care of it. As a result, he fired Rosa, thinking she wasn't doing her job. But she takes him straight to the apartment, only to find it in a terrible state. Feeling terrible, Ronnie Anne comes clean to Mr. Scully.

Sometime later, she was reprimanded by her mother, while Rosa forgives her. she then cleans the messy apartment, presumably as punishment.
