"El Jeepo"

 Last time we went to the yearly September fayre, we saw a number of army behicles on display. Mostly British, but some were American. Many of them had personal nicknames. Among them, a jeep aptly named "El Jeepo". With a strange critter meant to represent some animal, real or unreal. I thought it was funny anyway. Somebody has any idea what animal is this El Jeepo? I guess it's American, maybe Mexican? A wildcat, perhaps? A cryptid? An obscure cartoon character? For those who are into vintage army vehicles, army stuff, please let me know in the comments.
