In Digimon Universe: Appli Monsters, Gatchmon in the fourth episode, falls in love with (and totally an intentional product placement) what's dubbed as "Gatchi Sweets" or "GatchiMonaka", which is wafer biscuit with bean fillings.
Frequently across episodes, we also see Rei, one of the protagonist characters frequently drinking small packets of a "Choo Choo Energy" drink of some sort.
What exact is that, and does it have a real-world equivalent; physical thing?
... or is that drink totally and utterly fictional?
