Its a whole new mould, but I have no idea for the ballast.. I dont know if the shark from the pirate lagoon is an old one, I mean is there an older one than the lagoon shark? but here is how they float...
wow, thanks! Seems the regular shark is a tad bigger? (hard to tell from perspective).
Just seeing them swimming around together in your bowl looks ominous and creepy! I'd hate for a clicky to fall into that bowl of doom!
I want an army of sharks (both styles) to infest my piratical waters! I hope they sell it as an add-on at some point. Heck, I have to wait a whole year for the entire new pirate theme to get to the US, darn it!
Shark from the lagoon set has a metal ballast I believe. I recently got a newer shark (can't remember which set it came from) and I noticed the ballast was just solid plastic, not metal anymore. Much like the metal anchors being replaced with plastic. Seems to still get the job done though.
