One apparently normal day, Dr Eggman tries to steal the Chaos Emeralds from the Crystal Brighthouse, but his attempt fails so badly that he ends up sending the Emeralds to the human world counterpart of Equestria. Now, Sonic sets himself on a mission: to find the Emeralds and bring them back to Equestria before they fall in the wrong hands. But as he travels on this new human world, he also ends up meeting some faces that look very familiar... but are pretty different at the same time.

It’s the day of the first-ever Equestria Heroes Day Festival, a day where heroes can be celebrated for the small and large acts of heroism in everyday life. After hearing of the Mane 6’s superhero adventures, the Pippsqueaks and Violette Rainbow want to be superheroes themselves-- they even bought their own superhero masks (unaware of their magical components) and made their own superhero aliases. And with that, the fillies may get their chance at being superheroes after all, after they are called on the Mane 6’s next Unity Quest mission.

This time, our pony pals head back to Fernfield, reuniting with the Buddies and their kids and ready for their next action-packed adventure, which will be anything but relaxing as some new breeds of heroes are about to be unleashed.

An ordinary day at Fernfield Farms turns extraordinary when Budderball, Mudbud, B-Dawg, Buddha and Rosebud discover mysterious rings that grant them each a unique superpower, and the Pippsqueaks and Violette discover that the masks they bought at the festival each give them powers of their very own. And before you can say, “Buddies and ponies, assemble!”, the nine fur-ever friends unleash their amazing abilities and race to the rescue of Fernfield citizens in need, just like the Mane 6 have done on more than one occasion.

However, when the Buddies and all of their pony friends find out that Alterro has teamed up with a shape-shifting bully from outer space, named Drex, they realize that the entire planet could be in great danger. Now one very important question remains… will our heroes and their puppy pals, alongside some new friends, be able to succeed in kicking major tail without revealing their new secret identities?

A must-see story event packed with laughter, action and incredible new characters, G5 Adventures in Super Buddies proves when you use your wits and work together, you don't need superpowers to be a superhero!

Normally, Izzy Moonbow is a very cheerful and happy pony, but sometimes, things start to get just a bit too much for her to handle, which can quickly cause her to spiral if left unchecked.

Sunny Starscout has always been very patient and helpful for her, and now is no different once she starts noticing the signs that her unicorn friend is starting to struggle from all the sensory overload during a particularly hectic visit to town.

-------------------
This is partially based on my own experience, some things I happen to have seen on the topic, and also with the assumption that Izzy Moonbow is on the autism spectrum, which to be fair, there are certain 'patterns' she has that myself and many others on the spectrum pick up on. _{Or perhaps AuADHD, being both autistic and ADHD.}

After finding out the map they were given at the end of their last adventure will lead them to the Dragon Lands, the Mane 6 head there to let the dragons know that Opaline isn't a danger to them anymore. But while they are convincing the dragons they mean no harm, they are called on another Unity Quest... this time, it may be their biggest adventure yet.

When SpongeBob’s beloved pet snail Gary is snail-napped, a trail of clues lead him, Patrick, their sea-unicorn companions and the Mane 6 to the powerful King Poseidon, who is keeping Gary in the Lost City of Atlantic City. 

But… he’s not the only villain in this story that our heroes will have to deal with. Allura and her minion Twitch are here as well, looking for a fragment of a very powerful star that will lead Allura to other realms, and Sunny and her friends already have one of those pieces in their possession already. If she gets the rest of those pieces and combines them, she will be unstoppable.

On the mission to save Gary (and unknowingly, the entire ocean from Allura), the Mane 6 team up with Bikini Bottom friends, old and new, on a hilarious and heartwarming journey where they discover nothing is more powerful than family and true friendship.
