What is the last drop gag in toontown?
The last drop gag is the "Toontanic." Which is like a gigantic boat. Hope this helps.
Sorry, but you simply cannot get anything besides Toon-Up or Sound, depending on which gag you chose, while you are a free to play toon. However, if you get membership, you can get all but one gag in toontown. You can only have a total amount of three gags in toontown without membership. With membership, you can only have a total of six gags out of the seven. :)
