One morning, Yoshi and Birdo both woke up in their homes, simultaneously screaming, "NO!"
It happened again, they both had the same nightmare, the one where there were two versions of one dino callously leaving the other, leaving the other devastated. Yoshi's involved Birdo leaving him, Birdo's involved Yoshi leaving her. It stemmed from online rumors that they were dumping each other. They couldn't take it anymore, they had to get them off their back once and for all.
In Yoshi's house, the green one would watch Mario and Peach fight like spoiled brats ever since the moon incident. After the messy rejection, Peach almost abandoned Mario and then said nasty things to him ever since trip home. They would argue, blame and even shout at each other since, constantly wanting each other dead and shrieking the words, "I hate you!"
Everyone else saw it all go down and used the dysfunction to fuel rumors of other breakups. Targets of those rumors included but were not limited to Luigi and Daisy, Toad and Toadette, Wario and Mona, Donkey Kong and Candy Kong, and Diddy Kong and Dixie Kong. It went way beyond Mario canon too, with rumors involving various Nintendo couples. The whole internet believed if Mario and Peach's relationship could not last, what could?
In addition to Mario and Peach treating each other like the bane of their existence and acting like siblings that vehemently despised each other because they had to share their parents, there were even instances of them trying to injure and kill each other in public. This resulted in police officers having to constantly apprehend them and Toadsworth angrily having them both grounded for God knows how long.
Yoshi tried to help Birdo get her mind off of it and vice versa. They tried a relaxing stroll through the park, but noticed another breakup between two people they never knew, which only worsened the situation. They left in a panic and tried relaxing on the beach, but the same thing happened again, making them even more nervous.
Not even in a fancy restaurant were they spared from the dreadful sight of a nasty arguement and threats of abandonment. It seemed several men and women stormed out to leave their exes, the dinos couldn't take it anymore, they snapped and bolted out of the restaurant, screaming in sheer terror.
Clearly, the Honeylune Ridge disaster showed that the worst was far from over.
Back at Yoshi's house, they were both on the verge of contemplating suicide, but then Yoshi had an idea, "Birdo, why don't you move into my place?"
"How do I know it will work?"
"Everyone will see just how strong our bond is. They will then realize how wrong they are about everything."
"It seems like a wonderful idea! I'll get a moving truck and move in immediately!"
They embraced, their plan coming into fruition. The next morning, Birdo got a moving truck, packed up her stuff and moved into Yoshi's house. Their plans to shoot down and put an end to the rumors were underway. As they lived an everyday couple life, they were slowly but surely getting more and more internet users to take back their false claims.
