Am I thinking of the Right Cartoon?

I have extremely hazy memories of what I believe is this show. Did the main characters spend a lot of time flying around in an airship? And was there house right next to the lair of the bad guy, who spent a lot time trying to blow them up with a cannon, but kept missing despite how close they were?

And was there a lot involving magic crystals? I seem to recall a scene where the good guys fly into the bad guys lair in their airship to retrieve the crystals, but the airship was shrunk down really tiny. And they replaced the crystals with copies that were made out of salt or something like that.
