Some of these hints are wrong. There is actually no proof that Daisy "loves" Luigi. She is only considered to love him because she is the second most prominent female character.
Also, the koopa kids, or koopalings, are the adopted children of bowser, not the cousins. The Kong's don't have a definitive family tree, but Diddy Kong is said to not be Donkey Kong's son. The rest of it is pretty sound.
This quiz is way too vague on some of these hints and flat out wrong on others. For instance, the koopalings and koopa kids are NOT bowser's cousins, nor are Dixie and tiny Dk's cousins, or diddy dk's son. "A large bullet" being the clue for king bill is flat out confusing considering most people will think Banzai Bill, instead of the one variant of bullet bill that was only in a single level of a single Mario game. Same with "a large cheep" and " a more evil version of lakitu", I found myself thinking you meant boss bass or dark lakitu instead, or even worse, completely clueless with PhantaManta being "a creature that goes over the horizon". There's literally nothing to go on from that, you could've easily put "a shadowy creature that splits apart when hit" or something. There's plenty more wrong, but you get the point.
Diddy is not Donkey Kong's son. He already has a son named Donkey Kong Jr. Its spelt Dr Mario not Doctor. No one knows E. Gadd is named Elvin, so accept E Gadd instead. Lemmy, Wendy, Ludwig and the rest have been Bowser's kids for years they are never called his cousins and their first name should be accepted without having to put koopa or their middle initials. Your hints are too vague like a bigger bullet is Banzai Bulket not King or the one for Fawful, just say hes the villain in Bowsers inside story or Cackletta's sidekick. Blooper is a squid not a fish. So yeah fix your quiz.
Diddy Kong is not DK's son. He is a cousin like Dixie Kong. Please switch Koopa Kids to Koopalings. Ludwig or at least Ludwig Koopa should work for Ludwig Von Koopa and the others. Baby Donkey Kong is actually called Donkey Kong Junior. Some of these clues are very simple even if you haven't heard of. Like Mecha Bowser or Paper Mario. Also there is no such thing as Baby Bowser
