Cuddles-Giggles Relationship

Cuddles and Giggles have had numerous romantic experiences with each other throughout the series. They now appear to have a boyfriend-girlfriend relationship.

Remains To Be Seen
This may have been the first visible sign of their relationship. As Lumpy witnesses the zombified characters coming out of their graves, Cuddles and Giggles are seen eating a brain. They slurp a piece of the brain like spaghetti until their lips touch, making a reference to the popular scene from Disney's Lady and The Tramp.

Youtube 101: Subscriptions
Cuddles is seen subscribing to Giggles' Youtube home page, with a heart-shaped picture frame of Giggles beside his computer. However, Cuddles watches a video of Giggles apparently dating Disco Bear. Outraged by this, Cuddles gets second thoughts. He throws away his picture of Giggles and cries over his loss. Just as the video ends, it is revealed that Disco Bear was with a cardboard cut-out of Giggles instead.

The Carpal Tunnel of Love
Cuddles and Giggles fall in love, and Cuddles tries several attempts to show her his affection. Cuddles grabs a flower from Toothy's hedge hoping to impress Giggles, only for Lumpy to take his spot and develop an allergic reaction to the flower. On the bus, Cuddles draws a picture of a heart on paper. But before Giggles could see it, Lumpy grabs it and blows his nose on it, then lets it fly out of the window. At the cafe, Cuddles and Giggles share a drink, but get sick discovering Toothy's eye in the straw. Later, Cuddles and Giggles meet outside the cafe and nearly kiss, but get impaled though their heads by a pipe. The pipe hits a tree, and Cuddles' corpse slides down until it touches Giggles' lips, finally having "kissed".

I Nub You
Cuddles is seen pushing Giggles on a swing. Handy fails to push Petunia due to his lack of arms, so they ride a teeter-totter instead. Later, Cuddles and Giggles are seen holding hands, while Handy and Petunia have their bandages tied together.

Disco Bears All
The beginning of this episode shows Cuddles trying to put his arm around Giggles, but fails. Cuddles is then informed about Disco Bear's ad, which could teach him how to find love.
