For some reason, you guys seemed to like that picture of all the Super Mario toys from Penny Arcade Expo, so I figured I'd give you more of what you want. There's a store in Nakano Broadway that sells capsule toys -- excuse me. There's plenty of stores in Nakano Broadway that capsule toys, but this one has a huge display of Mario stuff out in the front.
Everything from keychains to figures to those little Sound Drops that make Mario sound effects when you squeeze them. Check out the Mario-in-a-turtle-shell in the pic at right.
Plenty more pictures, plus a bonus incredibly offensive, not-safe-for-work, who-in-their-right-mind-would-buy-that, only-in-Japan toy, below.
Finally, Mandarake's extensive line of products run the gamut from pure childlike Mario joy to the extreme depths of otaku fetish fandom. I've taken the liberty of censoring the picture below. Please do not click on the final image unless you want to see the full uncensored version splashed across your monitor. Please do not click if you have any shred of innocence left, as this picture will rip it directly from your soul.
