game Animal Crossing
Your touchpoint gyroid comes installed next to your house. This is where you save your game, leave items for the fellow human players, and the various other nefarious chores it can help you with. The touchpoint gyroids move in a slow 80's liquid dance starting from your purchase of the house. Their pace quickens upon the approach of the character that is associated with their house. It's disturbing.
Musical gyroids appear buried in the dirt the day after it rains or snows in your village. Supposedly made of clay, you would think they would more resemble the fabled golems, instead they are quirky almost robotic creatures. The musical gyroids will make on noise while wiggling and gyrating. Their sound is usually hinted at by their name, from the bovoid and it's lowing moo, to the tootoid and it's fartlike exclamations. There are (i think) 39 kinds.
A - Z Name List
Gyroids count as a type of furniture and can only really be seen when dropped inside a house. You can turn them off and on, BUT you can only have 14 turned on at once. Once you attempt to turn on the 15th gyroid in a room, another random one will turn off. They don't really count as a vital part of playing Animal Crossing but they are fun interesting little oddities that make weird sounds and seem like they were named by Willy Wonka.
My favorite quote about gyroids is when I got a msg from my roomate (about her touchpoint gyroid) proclaiming :
"I can't get the damn robot to hold the shovel."
