Here's my guess:

Despite the fact that the series was coming to the end of its run, Cartoon Network did contract Antonucci for three special episodes in addition to the four seasons near the end of Season 4's production run (Jingle Jingle Jangle, Hanky Panky Hullabaloo, Boo Haw Haw), and upon seeing the response to those, (or, more likely, just the first two), renewed the series. The contract for special episodes may also have come about because they suspected that the show was still popular, and wanted to make sure it was before they renewed it.
