Giggle is a young female Griffon from Griffinstone and the daughter of Gabby and Spike. She's also the middle triplet sister of Glare and Geoff.

Not so long after Gallus and Grandpa Gruff made amends with each other after their argument nearly four years ago, Gallus and Spike found the courage to propose to their girlfriends, Silverstream and Gabby, with a little help from their friends and family. Gallus' proposal took place at the beach, while Spike proposed to Gabby during "Power Ponypalooza", a Power Ponies convention. The girls reacted with pure joy, both crashing their fiancés with hugs and kisses. The two couples decided to have a double wedding, which took place in Mount Aris.

A few months later, Silverstream and Gabby were pregnant (Silverstream was pregnant for a second time; Galicia was a few years old)! They were both squeeing about how they were expecting babies and kept squeeing, while Gallus and Spike's jaws were on the floor. The two had many uncertainties and believed they wouldn't be good enough to be fathers (and Gallus didn't expect to have another baby), but with some encouragement from their beloved consorts, they put away the doubts and decided to enjoy every moment of this. Gabby gave birth to three Griffon-Dragon hybrids, two boys and a girl. With the help of Ocellus, Twilight, and A LOT of books about rare non-pony species and hybrids, Gabby and Spike discovered that the three bundles of joy were "Zilants'', also known as simply "Dracogriffs". According to their findings, like many other dragon hybrids, Zilants resemble their non-draconic parent more in their silhouette and general build. Like Griffons, their colors tend towards the more natural-looking and earthy. They tend to have a similar color pool to dragons, scales on their backsides, horns, spines, dragon-like tails, with feathers on the ends, wings that switch from feathers to skin halfway down, and draconic bird talons (meaning they look mostly like bird talons, but are shaped similarly to dragon claws). These hybrids are capable of breathing magical dragon fire, although their bodies are much less flame-proof than a full-blooded dragon's, but are still able to take in hot temperatures despite their feathers. Spike was happy to hear that because that meant he could take his children to the Dragon Lands without worrying they'll get hurt by the lava.

The middle one was a little girl that, like her siblings, looked like her mother in body shape, but had the wings and tail of her father. Just like Gallus and Silverstream's kids, Gabby and Spike's triplets weren't named right away. Of course, "Giggle" was just a nickname Spike gave his daughter. "Gillian" was her given name, though, nearly nobody called her that. Instead, she was referred to as either "Gigi" or "Giggle".

"Like mother, like daughter". That's the first thing that comes to mind when meeting Spike and Gabby's daughter, Gillian (nicknamed Giggle). Giggle is an extremely affectionate, adorable, and emotional little cub that is, undoubtedly, a spitting image of her mother. She's inherited Gabby's great love of helping others purely for the sake of it, as well as her high energy. Unlike her brother, Glare, she's surprisingly very good at math. She also really likes to cook and bake, although she's still learning. Much like Gabby, she's extremely kind, considerate, and helpful, and enjoys lending a helping claw. She really likes playing with her siblings and her love for Grandpa Gruff's stories is almost like Lil' Gruff's. Although, sometimes, even though they know it's not true, her brothers can't help but feel like she's their mom's favourite, to which Gabby highly disagrees. Much like her honorary cousins, Giggle and her family don't really have a stable house, for they go back and forth to Ponyville, Griffinstone, and, sometimes, the Dragon Lands, Canterlot, and the Crystal Empire - though they mostly go to the latter three for vacation. Still, Gabby and Spike are planning to have a house between the territories of their hometowns to be closer to their friends and families. Giggle likes all of those places for many reasons. Griffinstone, because she gets the chance to see her honorary family members, the Dragon Lands, because she loves playing with the dragon babies and the lava pools, the Crystal Empire, because she gets to see cousin Flurry Heart, and Ponyville, because she loves how ponies break into musical numbers and because she loves helping literally everypony she finds. Giggle is a mama's girl, true to her title.
