Rommonster

A friendly-looking, tentacled space creature with two eyes. Most major platforms style their design after aliens in classic arcade games like Space Invaders, rendering it purple and pixellated, as if in 8-bit graphics.

Samsung’s design resembles an octopus and previously featured a big-brained alien, à la Star Trek. Earlier designs from Google and Microsoft depicted more cartoon-like alien monsters.

May be used of topics concerning extraterrestrial life, outer space, gaming, and computing, but also enjoys a range of idiosyncratic applications, such as conveying a sense of weirdness, wackiness, or excitement, given that the emoji looks like it is raising its arms shouting Yay! on many platforms.
