Bizarre ice cream flavors should be the only flavors available in the Bar! Honey Mustard ice cream, anyone? Any takers on Durian, Cheese, or Grass? Not that Andalites can eat ice cream, but that's not the point!
Real-life weird flavors (found in Japan, of course!) include things like Wasabi ice cream. "Durian" is probably the only made-up flavor that might actually exist, now that I think of it...
And, I've never had Pistachio ice cream before, but I have been meaning to try it. I like pistachios, so why not?
