Ecnalubma

Note the anagram, frequently cited as imperfect mimicry

Ecnalubmae are vehicles that mimic the ambulance. Despite their similar appearances, ecnalubmae are actually more closely related to U-Haul trucks. The main way to quickly identify an ecnalubma is by the front of the vehicle: a true ambulance would say "ambulance" on the front.

Ecnalubmae are red, white, and blue due to their origins in Czechia. Unlike the ambulance's wailing wolf-like cry, they make a chattering sound. Like an eagle, but with a V8.
