This kit is the SD Mushamaru, the first release in the SD Gundam Musha Marusen series. It's a fun little unit that carries a takoyaki griddle on its back along with flags bearing food names. Those signature flags (nobori) can be made by cutting out pieces from the manual.
Remove the armor and you can put it in a light-armor form called Mushamaru. There's also a gimmick where you grab the top of the head and rotate it 180 degrees to change the eye expression — Mushamaru comes with three different eye expression seals. The backpack features a takoyaki griddle that flips 180 degrees, and the flags even have "takoyaki" written on them. Reassemble just the weapons and you can build a mobile takoyaki machine, and there's a bonus gimmick where you combine the arms, feet, and sword to form Tanwan Mode.
The articulation and color scheme are pretty straightforward, but the fun takoyaki machine gimmick and the flags are what really make it stand out. It's a kit that holds a lot of significance as the very first entry in the adorable Marusen series.
