Well, there seems to be a Spanish version as well (ingame). Might be a (very) rare case of an English Box and a Spanish game inside. MobyGames isn't a reliable source for 'does not exist' anyway, since they only list what they know (pretty much like HOL). Either way, if that is an Amiga game in the box, it's quite rare
