I don't always eat a healthy, nutricious, and delicious breakfast, but when I do, Rice Krispies are an essential part of it.
In English, those zany krisp rice boys shout "Snap, Crackle, Pop" (and thus they are named). As hard as I've tried, English is not the universal language. Alas, other tongues have assigned their own peculiar onomatopoeiae for these delicious morsels.
Spanish: Pim, Pum, Pam
French-Canadian: Cric, Crac, Croc
Finnish: Riks, Raks, Poks
Danish: Piff, Paff, Poff
German: Krisper, Knasper, Knuster
Afrikaans: Knap, Knaetter, Knak
Dutch: Pif, Paf, Pof
Those nutty Finns and their "Riks, Raks, Poks" - who hears that when they hold a bowl of cereal to their ear hole?
