Hmm… where have we seen this magical symbol before?

From the script:

EXT. — THE BOARDTROT — ENTRANCE GATES
As Hitch puts the padlock on the gate, we flash to the inside of the park and the Nova Shards as they sparkle and glimmer and and shoot out to create some magical mayhem but we only hint at it here.

As Hitch trots home with Sparky in a baby Bjorn, Sparky looks over Hitch’s shoulder and sees what looks like magical fireworks in the Boardtrot.

SPARKY
Oooooooooooooh! <POINTING EFFORTS>
Sparky points and tries to get Hitch’s attention but Hitch just giggles,

HITCH
I know you love the Boardtrot, Sparky! But we’ll be back there tomorrow! Silly little dragon!

Director's notes on this shot:

We see one Nova shard first, a slight twinkle forms around it, the core of the crystal intensify in light and colour, split screen with the other crystals and they starts glowing, a burst of light projects out of them fast. We cut to a down top camera angle as we see the lights crash into one point of the sky that sens a aurora halo over the place covering it with a luminesnce light.

Ref: You can probably refer to MLP139 for the treatment, the prisbeam x CM x wishing star

At the end we get a very wide view of the place before fading into the next segment.
