Emotibot, a robot created by Steve (in Comic 2), is capable of feeling complex emotions. However, Emotibot doesn't experience these emotions automatically; he (or a third party) must manually push a button on Emotibot's control panel that corresponds to a certain emotion (though for unexplained reasons, these buttons seem to change completely on a strip-to-strip basis). Since Emotibot's emotions are so easily changed, his behavior is highly erratic; he experiences frequent mood swings.
During Emotibot's nascent period, he experienced a few glitches, sometimes blasting Beaver in the face with powerful death rays. In addition, Emotibot once produced baked goods such as toast and bagels, but this function has disappeared.
