The Hydro Bounty delivers on a lot of features that I'd expect out of a set. It's a sleek submarine with some cool functional and decorative elements, features cool storage of mini-subs and a small mecha, and it comes with all six Ninjas and some extra characters. There are a few small design issues, but honestly none of them are bad enough to really turn me away from the set. It's an expensive set, but I think it does a great job at capturing the essence of the Ninja's undersea adventures.

PROS

• Six Ninja minifigures, full team is great for collectors
• Fun manta ray design, and octopus Prince Kalmaar is cool too
• Big submarine. Very hefty and swooshable
• Mech merges seamlessly in at the bow and pops out to look pretty cool
• Storage compartment for mini subs adds to play value
• Lots of extravagant details along the sub, like the porthole windows and dragon hilt / lantern designs on the side
• Clever function on the engines
• Decent amount of pieces

CONS

• Ninja scuba suit mouthpieces don't actually line up with the fig's mouths
• Bright light orange is a strange color choice for the mini-subs
• On that note, why does Nya not get a mini-sub? It doesn't have to be this set, but like everybody else gets a vehicle? We're just supposed to be satisfied that she got a dragon? Other headlining Ninjas have gotten vehicles and dragons in the same wave!
• Can be a bit troublesome to load in the mini-subs into storage area
• Engine function only works one way
• Don't have a lot of representation for the undersea villains, who's chariot is severely outclassed by the giant sub
• Pretty expensive, even if it is worth the value, it's a tough cost to meet for the casual buyer
• Hydro Bounty is almost too big, and yet it should be bigger with space for six Ninja mini-subs and a spacious bridge where the whole crew can lounge around!
