Cartoon Network rarely gives reasons as to why they end their shows
if they are not ended by their creators so there doesn't appear to
be a definitive reason as to why it wa…s cancelled.
Presumably it ended for the same reason any show gets cancelled,
the ratings weren't strong enough to justify the cost of making new
Interestingly enough its fourth season was going to be its last but
its popularity kept it going for one more season and a finale
