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.
Anvilicious: After playing the minigame "Bunnies Don't Brush Their Teeth" from Rayman Raving Rabbids, it's almost guaranteed that you'll be driven to frantically make extra efforts in improving your dental hygiene.
Nightmare Fuel: You'd be surprised at how much Ubisoft stretches the Y3-rating when the game contains some genuinely disturbing stuff.
"Rabbids Are Slow to React", while not scary in and on itself, it features a creepy, slow voice counting down ("3, 2, 1, Go") accompanied with an unsettling, maniacal laughter. There's no reason for this, either, it's just programmed like that.
"Rabbids Are Ticklish", has to be the most disturbing mini-game in the game. You are supposed to hit different quarters of the bunny's brain, each of which affect what he does (one quarter makes him scream, another makes his eyes widen), and all the while he stares at you creepily with an open mouth and...oh, God. Just look at it.
"Bunnies Don't Brush Their Teeth" can also be pure Nausea Fuel to those who are extra afraid of losing their teeth or the mere thought of having Cheshire Grin worms in their teeth.
Bunnies Don't Know How to Jump Part 2 from the first game is extremely frustrating. Not only do you have to jump, but you also have to swing the rope at the same time. This can be hard for people who don't know how to work with their own coordination. Plus, even if you jump before you even swung the rope, you still smack right into the chain as if you got hit by it while it was swinging! This minigame isn't really well recieved.
Little Chemist from the second game was also pretty frustrating going for the high score (which for those who never played the game, the high score cap is always 12,000 points). You have to shake bottles to reveal a symbol corresponding to symbols seen on a colored panel below your rabbid. The symbols come in two colors (yellow and purple), and there's three symbols for each color (spiral, rabbid skull, and burst). The problem with this minigame is that every time you start it again, the bottles are never in the same spot, so you always have to keep wasting more time shaking the bottles to see which symbol it is, even more so if you're not good at memorization.
