Four minifigs in a $40 Ninjago set is the kind of headcount that usually costs more — the Ninja Sub Speeder delivers on roster without making you feel robbed.
Four minifigs for $40 is a deal that stands out even by Ninjago's generous standards, and the Sub Speeder earns that A+ price grade without much debate. The submarine design has a clean, compact look that holds together well — not a showstopper, but a set that doesn't embarrass itself on a shelf either. The build itself is a solid afternoon: nothing groundbreaking in technique, but the underwater vehicle format gives it enough shape and structure to keep hands busy. Kids get a submarine, ninja minifigs, and immediate imaginative fodder — that's the whole recipe for a successful gift. The weak spot is long-term value; this one tracks as a slow mover in the secondary market, so the case for buying it is entirely in the enjoyment, not the exit. At its original price it's a fair trade, and that's really the story here.
