Waterfall

This is a sub-page of Prerelease:Undertale/Concept Art.

Areas#

Temmie's (frankly gorgeous) concept art of what seems to specifically be the marsh.

Sketches of various background objects in Waterfall.

Seems to be concept sketches of how Waterfall could potentially look. The 1st one seems to be what was chosen for the final.

Rather humorous concept art by Toby, featuring italicized captions and an unknown character at the top. According to him, this is just him "figuring it out"...

part 2 - marsh

water should be black because cyan
would just look like Shit (italicized, fancy font)

...And yet more, this time for Waterfall's marsh with some choice words for cyan-lovers (the art book hastily censors it to say "shaving cream", so the Twitter upload is provided instead). The final version of this area has cyan water anyway.

More beautiful concept art by Temmie of the marsh.

Unused drawing of Omega Flowey meant for one of the walls, presumably the text that describes a diagram of an unknown being. Was removed as it doesn't really make sense.

Concept art by Gigi D.G. of Mettaton's old house. According to Toby, this room was added late into development.

Temmie's concepts for Napstablook's house, with some possibilities ranging from a small hut, a mound, or even just a door on the ground. The house shape that ultimately got used (a tall, P-shaped house) can be seen in the center. In Toby's description, he muses about making the inside of Napstablook's house and Papyrus' shed the same, and never changing it.

Yet more Temmie concept art, this time of a room design.

Gigi's concept for Undyne's fish house. Toby liked all of these, but scrapped them simply because they wouldn't fit on screen.

Gigi's (and drak for the tail) final sketch for Undyne's house.

Concept Art	Final

Crude sketch by Toby of the interior of Undyne's house. The pet fish in the corner was supposedly removed for being "too weird though. It'd be like a bunny walking a bunny."

Crude mockup of Undyne's crag by Toby. This background would later be improved by Merrigo.

Really rough sketch of the view of Asgore's castle by Toby.

Rough sketches of various Waterfall objects, most notably the Bridge Seeds.

A LOT of tiles, both used and unused, from Kenju.

The first one presents a lot of unused tiles and objects, such as ladders, a pickaxe, crystals, a geode, cobwebs, different variations of the light-up mushrooms, support beams, a crystal mirror, and a tipped-over mine cart. The second image provides us yet more unused objects, such as ominous stairways, pillars, stalagmites and stalactites, more support beams, a hole, early bridge sprites, more detailed versions of the Bridge Seeds and the bell, a luminous tree, and glowing water sausages.

Toby regrets not using some of these assets in the final game. Kenju was only told it was a cave-like area, which is why so many of these objects seem intended for an old, abandoned mine.

Characters#

Undyne#

Toby's very first drawings of Undyne, with a very, very different design.

2 pieces of concept art for Undyne. This iteration of Undyne was far more fish-like than the final version. The design was based on an Axem Ranger from Super Mario RPG: Legend of the Seven Stars.

Toby also said in a later tweet that he considered Undyne's head being realistic, looking identical to a real fish's head. There is no art of this concept.

Various overworld poses and notes for Undyne. According to Toby it took him a while to figure out her personality (she was originally more aggressive, had several different accents for a time, and at one point really into fashion and singing), and he only figured it out while writing her pre-battle monologue.

Temmie's old design for Undyne in her armor, which Toby tweaked as she looked too much like a generic knight.

Early versions of Undyne's final overworld sprites, most notably without the longer lower wear and stark lighting of the final.

Various early Undyne faces by Toby, some showing some early designs.

Various early concepts for both Undyne's battle sprites with armor and without it, compared to Papyrus and Toriel's battle sprites.

Toby's early designs for Undyne's date attire. The top ones were Toby's first design, which Gigi stated made her look like she's going for a jog instead. His friend Jones suggested that she wear a jacket on top of it, which ended up being the final design.

Various unused overworld sprites of Undyne maskless in her armor, including her talking and her hair blowing in the wind. Interestingly, judging by the placement of these sprites in the art book, these were most likely some of the last regular sprites of her made.

Early concepts for Undyne the Undying's appearance. She originally had completely vertical hair - which was only removed as it wouldn't fit on screen - and briefly had a mermaid tail.

Gerson#

Early concepts of both Gerson and his shop. Toby drew his faces, and Temmie did everything else.

Temmie#

Betty Kwong's original design for Temmie, drawn before Tem was attached to Undertale. This design was drawn by Betty in a livestream in which she drew what she thought her online friends looked like, and Temmie loved it so much that she adopted it as a mascot for her social media for a long while. Eventually, this design ended up in Undertale as Temmie's self-insert ala the Annoying Dog to Toby.

A few of Temmie's sketches of herself, made before joining the Undertale dev team.

Temmie's early ideas for the Tem Shop, showcasing some slightly different box designs.

Toby's early sprites for the Tem Shop, heavily referenced from Temmie's concept art, along with some unused faces.

early ver of...... TEM SHop!!! Major differences include a different pattern for the trash can, no label on one of the boxes, and no framed picture of the Annoying Dog.

Seemingly early versions of Temmie's overworld sprite.

Unknown sketch of Temmie, in both intended use and artist.

An extremely obvious placeholder drawing of Temmie found in the Fangamer-published book Legends of Localization Book 3: UNDERTALE. There is no drawing by or of Temmie in the book, so this is probably just an actual placeholder from Undertale's development.

Aaron#

One of Toby's friends asked him to put a monster in that is "very muscular and strong", so he told Temmie to draw a muscular horse design because she hates muscles and horses.

Shyren#

The original versions of Shyren and her manager's battle sprites, featuring some weird looking eyes that, judging by the caption, Toby is glad he removed.

Multiple Characters#

A couple Waterfall characters, including an earlier, more professional-looking (and pink) version of Onion-san.
