* GoddamnedBats: The series is littered with them. Special mention goes to the red bats, the tornadoes, and the water snakes in the sequel.
* GoodBadBugs: The game engine could only support a certain number of enemies on the screen before it stopped loading more. In the [[ThatOneLevel toy room]] running past enemies without killing them would make more than half the enemies simply not load.
* PortingDisaster: The NES port. But given Color Dreams (or Wisdom Tree) resumé, it was to be expected.
* ThatOneLevel:
** Nature reality in ''2'' has a heavy focus on platforming, with large tracts of the level filled with large instant-death pits. This is made worse by the birds with strange flight patterns, shrubs that pursue you, and tornadoes which can't be destroyed and deal massive damage.
** The toy room in Dream reality is a long hallway with no special tricks or platforming but a massive number of enemies supported by ceiling-fired rockets. Fighting through this room is a battle of attrition unless the player decides to cheat and just run for it.
