Okay, so let's go again...

Look like King Trollex's techno fish have the string ? Hmm...

Maybe each tribe has a "sacred" animal that protects the string , no? I mean, take the Pop tribe :

Mr.Dinkles is clearly SUPER important for them.

I propose you to review the episode "The Party Crashers" in TTBGO. Do you see how everyone is clearly in panic? Not just Biggie!

If Mr.Dinkles was protecting the string?

And for all those who will say "Mr.Dinkles does not have hair!" I stop you right now:

he has hair.

Oh and:

Enjoy
