In an interview with the game's producer/scenario writer Hiroyuki Takahashi and director Shugo Takahashi published in the 1993 Megadrive Fan Attack Special book, they stated that the enemy "Paste" (called "Bubbling Ooze" in the English localization) was originally going to be named "Slime". Its name was not included due to copyright issues, so they tried other options to name it like "Ooze" or "Gel", neither of which got picked. They later came up with the name Paste, while the English release gave the enemies the unused name "Ooze". It's possible that 'Slime' couldn't be used due to a copyright for the iconic Dragon Quest enemy of the same name.
