Not as he is, no. When I first made him a few years ago, he was just meant to look creepy-cute and say either lines from the HELP_tale comic or glitched versions of his in-game dialogue. However, I started working on him again recently! I'm still working out where exactly I want to go with him, but when the update comes there are going to be some big and small differences (like he will be much easier to pet and will have network updating, have a user stats menu, talk at/respond to other ghosts). I don't know that it will be possible to "save" him, he is after all a Flowey. But I do want to be able to make him happier. I'm active on the @ukagakadreamteam Discord, and when the update is ready for release I will definitely be posting about it here.

There ya go. In there are .Nar files for f_lowe_y, and f_lowe_y_quiet, a stripped down version that does make any noise (the original is a noisy little shite because I like them that way). As well, I included a .zip of my undertale themed balloons. All ya gotta do to install them is drop them onto an active ghost, they should do all the work. (if not, let me know and I'll make the unarchived versions available)
