YMMV: Zig & Sharko
- Designated Hero: Sharko. In "Marina's New Friend", he forces Zig to masquerade as another mermaid, endangering his girlfriend, does the same thing in "Sharko and His Folks" because Sharko's parents do not accept of his Interspecies Romance, shaves basically everyone on the island and almost shaves Zig, and then uses him as a replacement for dorsal fin in Hair Story just to make a wig for Marina, openly flirts with Manic Mermaid in the "Manic Mermaid", despite that Marina is his girlfriend. In "Goin' Home", Sharko cries at how he misses beating up Zig.
- Love It or Hate It: The shows case, just like Oggy and the Cockroaches.
- Moe: Marina and Bernie.
- Ugly Cute: Zig.
- The Woobie: Marina in the episode "A Tale of Two Legs".
- Sharko in "King Neptune's Court"
- Jerkass Woobie: Zig in... pretty much every episode.
- Informed Species: Zig looks nothing like a hyena, which is he said to be.
