Well, this was a tedious story if there ever was one. The Turtles visit the amusement park, free Monsterex by accident and then the entire issue is just a dull chase scene through the various rides. I can’t imagine why Monsterex would even bother fleeing, as he was shown to be invincible to everything but the sun in their previous encounter and handily thrashed the Turtles in battle. Delaying their fight only served to kill time before dawn and facilitate a hasty conclusion.
