Is there any sequel to Jungle Wa Itsumo Hale Nochi Guu FINAL?

Jungle wa itsumo is probably my favorite anime series, I laughed a lot, I liked the characters, I loved the opening and the ending. After watching the 26 episodes, I found out there were 2 OVA series, so I watched Deluxe, I laughed even more, it was even more bizarre than the original series, then, I watched FINAL and I loved it, liked the OP, the new characters, it made me laugh even more than Deluxe, but there was something that looked weird for me, the "SEE YOU AGAIN" thing at the end. After doing some research, I haven't found any sequel, so I thought that maybe they have changed the name, but, since I didn't find anything to refute my theory, not even in the Other Wiki. Then, I decided to ask here, maybe you know if there is a sequel, and if you know it, please, tell me! There must be some kind of conclusion to the series!

Unfortunately, there isn't. That's probably why they called it "FINAL". I suspect they ended it like that just in case they got clearance for another series/OVA after that.
