These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Viva Piņata
Animation Age Ghetto: Main reason why the game is so off-putting. It's too hard for kids, and too childish for adults.
Broken Base: The TV show fandom and the game fandom. Yes, they exist.
Cult Classic: Both the games and the TV show. The TV show is considered surprisingly good for being something done by 4Kids. (It probably helped that it wasn't exactly being translated from another language and subject to as much Bowdlerization as the usual 4kids fare.)
Sour Crowlas are normally benign compared to other sours. However, if one comes into your garden and you have a sick piņata in there at the same time, smash it or scare it away fast. They're effectively mini versions of Dastardos when this happens.
Designated Villain: Langston Licktoad in the animated series. He's indeed always trying to catch Fergy (and Paulie) and force them to go to parties where they'd be smashed up. But it's just his job.
Some Ruffians have brown-colored tattoos on their hands and feet. At first they seem to simply add to their nastiness, until you realize what Ruffians probably do to captured piņatas filled with chocolate.
Pigxies are the sworn enemies of Rashberries and Swananas. This could suggest they're horrified of what they have created.
Game Breaker: The Wishing Well in Trouble In Paradise. Throw in 1000 Chocolate Coins, and you're pretty much guaranteed to receive several coins worth 2500 Each in return. Did I mention that the value of these coins can be increased by Five times just by placing a cheap item in your garden?
All sour piņatas; they spit poisonous candy in your garden, and they'll keep coming back until you're able to tame one.
Whirlms, requiring only a small patch of dirt or grass to settle in, are guaranteed to automatically join your garden every now and then. If you don't get rid of them, they'll be followed by Sparrowmints.
Any undesired piņata qualifies. They might eat your fruit or hunt your resident piņatas in order to stabilize themselves, whether you like it or not. Said unwanted residents might also scare off or start fights with other piņatas. The only solution is to brutally smash unwanted visitors with a shovel to keep said species away for a while.
This is fixed in the sequel, where you can set the Bouncer Board at the corner of the garden to repel a given piņata from showing up at all. But only if you've already got the Master Romancer award for it.
Jerkass Woobie: Dastardos in the gameverse. Sure, he's a jerk who kills sick piņatas, but he was taken from his family against his will and turned into a husk of his former self by Professor Pester. Not to mention no one knows who he actually is, so he'll probably be estranged from his family forever...
After episodes like "My Pal Langston" and "Langston's Jameleon Cousins", Langston qualifies as well.
Les Yay: Leafos supposedly wrote the descriptions in the Journal, yet one of the entries talks about kissing a girl...
Player Punch: If you've grown close to one of your piņatas, maybe named it and dressed it, you might feel badly hurt if they get smashed.
Squick: The game doesn't keep track of families, so not only is Brother-Sister Incest a possibility, but you can even mate Piņatas with their own parents or children. To be honest, there's so much inherently wrong with the game that there's even a VGCatscomic that sums it all up nicely.
Stop Helping Me!: You're likely to be overhelmed by pop-ups early in the game; it gets better.
