Fan Works / Attention Deficit Ooh Shiny

Bolt

The Bolt Chronicles: In "The Service Dog," Carmen the chihuahua is yappy and easily distracted, abruptly changing the subject on several occasions when she talks and periodically breaking into song.

The pug in Calvin & Hobbes: The Series rarely holds onto one mood for long. As Hobbes puts it:
"He's a furry little emotional rollercoaster."

Joys of the Parenthood - The Țepeș Edition: Being easily distracted like all other three-year-olds, Lisa has little faith in bringing Adrian to a council meeting.
"I'd prefer later," Lisa frowned. "When he's capable to look after himself."
Dracula looked at his wife, furrowing his brows. "None of them would dare to harm our son, love. They know I would tear their pathetic souls to shreds if they laid a finger on Adrian intending to harm him."
"I meant his attention span," Lisa pointed at the toddler in vampire's arms who had abandoned Dracula's collar when his attention was drawn to older vampire's pointed ear and soon tiny fingers with sharp beginnings of nails dug into the flesh, tugging.

In Dragons, Butterflies, And Who Knows What Else?, Valentina completely forgot about the life-changing news that she was pregnant after enjoying a pair of Gronkles sparring in the streets.
Fantasy of Utter Ridiculousness: Alice is gifted with a scarf early in the Extra Stage. Several times after, she gets distracted enough with its quality that several conversations fly right over her head.

Ryuk in the original Death Note Abridged by TioH and Dargonakis.
Light in Death Note: The Abridged Series (kpts4tv):
Ryuk: ...now what you need to know about the Shinigami eye deal is...
Light: [thinking] ...shoes... I need to get shoes...

In Age of Dragons, Kathan Adaar is a Qunari Inquisitor prone to going off on random tangents and forgetting what particular quest he is on at any given moment. Somehow he manages to be the smartest guy in the series anyway, proving that sometimes The Cuckoolander Was Right.

In The Feel of Feelings after Harry is released from an unjust two-year stint in Azkaban and goes to Gringotts to claim his inheritance he spends several minutes playing with the Black and Potter rings before putting them on, while his reaction to all the galleons in the Potter vault is "Ooh, shiny."
In Ignore the Dementor Harry turns into a dementor body after being Kissed by one. He decides that they must be fascinated by shiny objects after spending several minutes staring at Dumbledore's purple robe with silver stars on it.
Shadows and Light:
...[Harry] rolled his eyes and decided not to try to say anything unless Ash got distracted by something shiny.
In Growing Up Kneazle, Harry, having been raised from a young age by Arabella Figg's resident Kneazle pride, is easily distracted by shiny objects and yarn balls.
In Wizard Runemaster Harry is usually very focused, right up until he spots a bit of magic he's never seen before, especially runes. At one point it took Onyxia promising to strip naked to get him back on track after he stopped warding their new base/home to study an old ward stone.
In Two is a crowd Harry and his friends are playing a magical version of hide-and-seek.
Whatever the reason, [Luna's] hiding ability was incredible, and so far Michael hadn't been able to spot her. Luckily, she often became visible again because a beautiful snow flower, a cute hare in the snow or some other fancy something or someone distracted her.

In The Lion King Adventures, the Uchoyo Diamond has this effect on animals. Simba uses it to take over the entire pride.

Ultra Fast Pony uses this as an occasional gag, rather than a consistent trait of any one character.
- In the opening episode, Twilight Sparkle sets off to save the world from an impending apocalypse. One run-in with Rainbow Dash later, she completely forgets about the apocalypse and makes it her goal to destroy Rainbow Dash instead.
- In "Copywrong", Rarity devises a Zany Scheme to wreck Fluttershy's modeling career, but the scheme immediately derails and ends with punching Rainbow Dash rather than hurting Fluttershy in any way.

In Time Mix Up, it's revealed that Naruto's canonical hyperactivity is him when he is under medication. Without medication, he's practically uncontrollable, something that Sasuke, Sakura, Zabuza, Haku and Tazuna's family all witness firsthand when Naruto's meds run out and a Peggy Sue-ed Kakashi forgot to restock on time. Turns out that both his Uzumaki genes and his status as a jinchuuriki gave him such high amounts of chakra that it channeled into ADHD-like symptoms so strong he had to be put in a padded room at age two to avoid injuring himself and others, and the medication is his only way not only to have a normal life but also a normal life expectancy, as his body wouldn't be able to take the constant tension and lack of sleep this level of chakra would give him.
Yet again, with a little extra help: "Ice Cream People!!"

In Luz Belos: Princess of the Boiling Isles, Luz being diagnosed with ADHD is one of the contributing factors to her lack of skill with magic, having gone through multiple magic teachers (Lilith included) before managing to make any breakthroughs with Eda.

Referenced in What Your Favourite Cure Says About You; the list claims that those with short attention spans are most likely to pick Cure Sparkle as their favourite Pretty Cure.

Chives the Dog, a minor character in the Sonic X fanfic Don't Keep Your Distance. Incidentally, she seems to be the only Mobian child imprisoned in a diamond mine (along with the main characters) who doesn't mind this line of work.
Brutally parodied in Sonic F:
Chris: Cream! Aren't you still mad about—
Cream: I'm only six years old. I have the attention span of a hamster, so I've forgotten why I was angry— OOH A SHINY OBJECT!

This fanfic depicts Pink Pearl as having ADHD, as a contrast to the autistic Crystal Gem Pearl.

The Hospital Toys: In "Soldier School", the Goblin can't help but squirm and make noise during the lessons. He doesn't mean to disrupt, he just had too much energy. The Strongman gets the idea to loan him his cat toy to fidget with, which helps the Goblin focus. Later on, the toys learn about ADHD from one of the kids in the hospital, and they figure that maybe that's why the Goblin can't sit still.

Momoko from Wedding Peach Abridged.
Momoko: It must be hard on Yosuke [to clean the Olympic length pools all by himself]. (pause) Hey, this ring gets so shiny when you move it around!
