I know a bank where the wild thyme blows,
Where oxlips and the nodding violet grows,
Quite over-canopied with luscious woodbine,
With sweet musk-roses and with eglantine:
There sleeps Titania sometime of the night,
Lull’d in these flowers with dances and delight;
And there the snake throws her enamell’d skin,
Weed wide enough to wrap a fairy in:
And with the juice of this I’ll streak her eyes,
And make her full of hateful fantasies.
Take thou some of it, and seek through this grove:
A sweet Athenian lady is in love
With a disdainful youth: anoint his eyes;
But do it when the next thing he espies
May be the lady: thou shalt know the man
By the Athenian garments he hath on.
Effect it with some care, that he may prove
More fond on her than she upon her love:
And look thou meet me ere the first cock crow.

A Midsummer Night’s Dream, Act 2, Scene 1

So one of my headcanons is that one day Jack will realize he’s been pining for Bitty, and so to soothe his sad-feels he adopts a little dog.  He names her Puck.  No that’s not a Shakespeare reference, that’s a hockey reference.  She happens to be modeled after one of my work babes who was rescued from a fighting ring, and often gets scared in new places; until you put clothes on her and then she comes to life.  So I decided Puck is the same, and Chowder sends her a little shark costume. I finally decided to draw Puck. You will probably see her again…and her future sister named Pie.  

Edit: Okay thanks to the lovely and very helpful @gabricl it should now be clear. :)
