Poptropica/YMMV


 * Anticlimax Boss: On Super Power Island, the order in which you fight the five villains can create this scenario. Copy Cat, Crusher, Speeding Spike and Sir Reberal all pose a significant threat. Ratman can...talk to rats. And only rats. He also goes down in one hit, and unlike the other One Hit Point Wonder, Speeding Spike, you don't need to be particularly skillful to beat Ratman.
 * Genius Bonus: On Red Dragon, the haiku master Basho has a banana plant next to his hut. The real Basho took that name from his favorite banana plant.
 * Nightmare Face: THE JERSEY DEVIL AAAAA
 * That One Level: Greg's Twisted Wizard game on Wimpy Wonderland Island. The ogres are fast, attack in numbers, attack from all directions, and you WILL die if your walls aren't strong enough to hold them off while you kill them with lightning. And God help you if your thunderbolts miss even one of them. Oh, did I mention you only have one life, instead of three, which means that if an ogre gets you even once, you have to start over? And if your inner defenses break down, the ogres become even faster than they already are? Have fun.
 * Snoopy's Piano challenge on Great Pumpkin, the dots fall too far apart, the piano keys are too close together, and when dots are close together they fall in-between the black and white keys, which are stupidly close together, the bar instanly drops all the way if you miss the first dot and Snoopy makes annoying pained expressions if you are losing making the mini-game harder than several boss battles.
 * Unfortunate Implications:
 * Unfortunate Name: An example of one of the horrible names you can have is "Lazy Eye." Also "Creepy Gamer."
