First, I need to verify if Zootubex is a real product or a mistake. A quick search shows that "Zootopia" is the movie, but "Zootubex" isn't recognized. Maybe it's a typo. Next, "repacks" often relate to games. For example, repacks of PC games are common, using tools like PowerISO or RePack tools. The user might be referring to a repack of a game, possibly numbered 40 in a series.
