Description

Group founded on 02/14/2019 | Welcome to Undertale Universe! | About the group: | In this group you'll find Undertale and Undertale Alternate Universe-related clothing. You can discuss about Undertale and AU topics in the group wall, find other roleplayers or just have a good time, as long as you keep it nice and friendly with each other. | How to get a rank: You can get any obtainable rank by simply asking for it on the group wall or by pming one of the owners! | About the game: | In this game, you'll find various maps to roleplay in aside from the standard Undertale map. We currently are at a count of 500+ Morphs, and more are being added in the future! [Please remember that making a game takes a long time, and there is a lot that has to be done.]

2 measurements spanning 39 days, net -2. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 245–247 and does not start at zero.
