Happiny 

Happiny (Japanese: ピンプク Pinpuku) is a Normal-type baby Pokémon introduced in Generation IV.

It evolves into Chansey when leveled up while holding an Oval Stone during the daytime, which evolves into Blissey when leveled up with high friendship.

Happiny is a small Pokémon that is shaped like an egg. It has a soft, smooth, light pink body. On top of its head is a curly outgrowth that resembles a ponytail, with a dark pink band around the base. The appearance of this curly growth of hair often annoys Happiny. It has three round bumps on its forehead. There is a pouch around the lower half of its body, which resembles a diaper. The pouch is red with a white stripe around the top.

Happiny's pouch is rubbery and flexible, enabling the Happiny to put things into it with ease. As it cannot produce Eggs yet, it makes up for it by carrying a white, Egg-shaped stone in its pouch to imitate Chansey and Blissey. It may give this stone to people whom it likes, and it has a habit of wandering around people's feet and causing them to stumble. Happiny is shown to be extremely strong in the anime, as one has been seen lifting heavy things above its head. Happiny is a female-only species with no male counterpart.

Happiness Hangover 

The crappy depressed feeling that comes after a time of great happiness. Like a hangover from alcohol, minus the alcohol.

Ryan: What's the matter? You seem a little down.

John: Yeah I just have a happiness hangover.

Ryan: Man I'm sorry, those are the worst!

The Center of Our Happiness 

In an erotically blessed couple, the woman's clitoris, focus of all devotion, from which emanates such intense energy, joy and transcendent oneness that her lover can think of nothing else. ... Excuse me. What were you saying?

In the middle of the day, apropos of nothing, she suddenly blurted, "the center of our happiness" and he knew exactly what she was craving.

I am you, I am just like you. That’s why I was attached to you. I wanted to give you happiness. I’m sorry I misunderstood your happiness. 

Kaworu from Neon Genesis Evangelion

When somebody says “ Everything is simply a shape, a form, an identifier to let others recognize me as me! But then, what am I? Is this me? My true self? My fake self? What is it that I am? Nobody understands me!” You just go “ I am you, I am just like you. That’s why I was attached to you. I wanted to give you happiness. I’m sorry I misunderstood your happiness.”

Hoops of happiness 

A state of happiness or glee in which you jump through imaginary, enlarged hula hoops suspended in the air.

When I finally found the title to an old video game that I enjoyed during my early youth I couldn't help jumping through hoops of happiness!
