Adventure Time > BMO, Life Given Objects (and more)
Inanimate Object Characters List | Entry: 84
Although Adventure Time features a couple more inanimate object characters (e.g. Neptr and Clock Face, which I won't cover), the most prominent one is BMO, a (multifunctional) sentient video game console system. BMO is one of the main characters.
Noteworthy, too, are the Life Given Objects. They are objects or plants that were given sentience by the Ancient Sleeping Magi of Life Giving (aka Life Giving Magus). The objects appear in several episodes across the series. Here's is a page that lists them all:
