71366 Boomer Bill Barrage Expansion Set is a Super Mario set that was released on August 1, 2020.


Banzai Bills are a larger variety of Bullet Bills that first appear in Super Mario World. Their attack pattern usually consists of shooting from off-screen (though occasionally, players can see them being fired from Banzai Bill Cannons) where a firing sound is played to alert players that they are incoming, and they travel toward players in a straight line. To avoid them, players can either jump on higher platforms or duck in lower areas of the stage. As with all Bullet Bill varieties, jumping on them or using a star on them are the only ways to defeat them, as they are immune to fireballs and break out very quickly if they are frozen with ice balls. While Banzai Bills share the same black coloration and physical characteristics as Bullet Bills, Banzai Bills lack arms and have a mouth in the form of a shark smile. They are the second-largest derived species of Bullet Bills, after the King Bill. The word "banzai" is a Japanese interjection mainly used for jubilation or celebration, frequently translated as "Hooray!"


The terrain is uneven, as some of the 4×4 grassy nodes are supported by earthy bricks, one with only a single layer of them and another with multiple layers. The latter node is, by default, followed by two more 4×4 nodes ordered from highest to lowest, one of which sometimes supports a Shy Guy. A small tree is intended to occupy one of these spaces, but is on the highest by default. The largest green node is at the ground level and usually lies opposite to the three 4×4 nodes. It is intended by default to carry a Super Mushroom sitting on a brownish block, but trading their place with the Shy Guy’s is welcome. The rest of the ground level consists of blue plates representing water.

At the water’s centre lies a brownish swing bridge with one brownish node on both ends, one which has studs to support Mario and a studless one that is harder to use but offers more coins. Both nodes have a grey gear underneath them, which will interlock with those in the structure opposite to the bridge. Scanning either of the action tiles on these nodes plays a dramatic song from Super Mario Bros. and puts a determined look in Mario’s eyes, because opposite to the bridge is a stack of two more grey cogs holding a pole that is holding two transparent suspenders, both of which carry a Banzai Bill. The default objective is to safely spin Mario on the platform as fast as possible until the dramatic song stops, which is challenging because completely rotating the bridge will also spin the Banzai Bills in a circle formation, potentially either obstructing or knocking Mario off of the bridge.
