Many children find gross-out humour very funny, and attractive.
Now, you may have gained the impression that BorgCo is a soulless, mechanistic, monomaniacal entity*, but that doesn't mean we're beyond exploiting an opportunity to insinuate yet more technology into your society.
So, we have designed
a range of dispensers for disinfectant compounds that have the external appearance of Disney™-type "cute" monsters.
They vary from Mugwai-sized units up to versions of Wookie dimensions, but what they have in common is (a) they are capable of limited verbal interaction, and (b) they dispense Sanitizer in a "disgusting" way - through a bodily orifice.
So as a child walks past, the effigy detects it and says "Baby Yoda sneeze now will ! " If the child places its hands in the correct position, then Yoda will indeed "sneeze", spraying their hands with green or blue or purple "mucus" - actually, a child-safe disinfectant.
They would be placed in schools and other public spaces.
Hilarity ensues.
*and you would be entirely correct.
