Super Smash Bros 4 Characters: Mario, Luigi, Princess Peach, and Toad Screenshot Celebrates Super Mario 3D World Launch (PICTURE)

Super Smash Bros 4 director, Masahiro Sakurai's new 'Pic of the Day' pays homage to everyone's favorite plumber as today marks the day Super Mario 3D World was released in Japan.

"Pic of the day. Super Mario 3D World is out today in Japan! To commemorate the occasion I had these four…people(?) come together in a group shot," Sakurai posted on Nintendo Miiverse. See the picture here.

The four characters spoken about in the image are: Mario, Luigi, Princess Peach, and Toadstool.

Sakurai recently revealed a new level in the upcoming game that was Super Mario Galaxy themed.

"Pic of the day. A new stage, Mario Galaxy!! The pull of gravity emanates from the center of the planet, so this will require using brand-new tactics," the director posted to the Nintendo Miiverse. See the picture and posting here.

Last weekend, Mario creator Shigeru Miyamoto revealed that the Super Mario Galaxy series is not necessarily finished even though they have moved on to the 3D World series and New Super Mario Bros series.

"Just so there is no misunderstanding, I should point out that this doesn't mean we'll never make another Super Mario Galaxy game," Miyamoto said in an Iwata Asks session. "The same team can't make both at the same time. And we can't bring in a second party and slap the name Super Mario Galaxy on it."

The two series' are distinctly different as the Galaxy games have an open world 3D adventure feel, and the New Super Mario Bros and 3D World are more of a 2D platformer.

"Personally, I would like to take on a variety of new challenges with Super Mario Galaxy and design 2D Super Mario games in an easy-to-understand way within certain restraints," he continued.

The new SSB game already confirmed 18 characters: Mario, Luigi, Link, Samus, Kirby, Fox, Pikachu, Bowser, Donkey Kong, Pit, Olimar, Toon Link, Princess Peach, Sonic the Hedgehog, MegaMan, Marth, the Female Wii Fit Trainer, and the Villager.

The website lists the Wii U date as Dec. 31 2014 and the 3DS version of the game as being available on May 16 2014 although no official date has been revealed by Nintendo.

SSB4 Wii U is $59.99 and SSB4 3DS is $39.99.
