Jellyfish

The inclusion of these marine obstacles across the Pac-Man World franchise and its contemporary releases reflects the era's transition into detailed 2.5D and 3D aquatic level design. In Pac-Man World 2, these creatures are strategically placed in levels such as "Coral Reef" and "Shark Attack," where their glowing designs assist players in navigating low-visibility depths. Their movement patterns require players to master swimming physics, timing their maneuvers to slip through tight gaps.

In Blaster Master Enemy Below, the sprite design adapts the classic Sunsoft aesthetic, utilizing simple vertical movement loops that challenge the player's submarine maneuvering in Area 5. Meanwhile, the iterations in Lost Vikings 2 and its 32-bit upgrade Norse by Norsewest The Return of The Lost Vikings require players to utilize specific character abilities, such as Scorch's flight or Olaf's shield, to bypass them safely. In the Shark Tale adaptation, they contribute to the reef's bustling, obstacle-filled environment. Collectively, these appearances demonstrate how developers utilized simple marine fauna to create consistent, visually distinct pacing hurdles across diverse platforming engines of the late 1990s and early 2000s.
