InstaPix

InstaPix is a social media network within Celeste's universe, similar to Instagram in real life. Theo makes gratuitous use of the platform, uploading various photos from his life, like of him venturing out himself, Celeste Mountain's landscapes, or him being with Madeline. He goes by the handle @TheoUnderStars on Instapix, which is also the handle for an Instagram account with the following photos. His bio reads, "Sometimes you eat the bear and sometimes, well, the bear eats you."
