Lucky and Patchy 3: Magical Space Pockets

In this thrilling installment of the Misadventures of Lucky and Patchy, our protagonists notice a strange Yukari-like gap appear. Logically, Patchy deduces that it must be a pocket dimension, instead of the work of Yukari. Lucky then proceeds to wonder if it functions like an actual pocket, having such properties as "where you store phones and stuff while you're walking around." She then proceeds to walk up to the pocket dimension, while Patchy wonders why, and extracts a sunflower from said dimension. Patchy, after hearing about how pockets typically contain quarters and wrappers, logically assumes that a new wrench can be extracted from the pocket dimension, by depositing her old one inside it. Unfortunately, her assumption is incorrect, as she extracts some "random object" aka a sandwich. She then proceeds to say "What," most likely to indicate that she is confused. Lucky then reveals that she has previously warned her about the dangers of pockets (and she has in the third panel, saying that they can be random). We also get a special cameo from the author of this creation, Pikachuun, entering the dimension and extracting a magic wand from it, which may or may not be the star rod from the Kirby series.
The theme of this comic is most likely related to the unpredictability of life as a whole, demonstrated best by how a wrench was transformed into a sandwich.

Bonus points if you get the reference with this comic's description (hint: it's also in the comic).
