What morph is my Pacman?

[monster]

When you look on his right side that huge bulge is probably ingested substrate and if he hasn't went to the bathroom lately it could be because the lump is impacted and preventing him from going. All though some people say use moss it isn't a very good substrate for these guys due this happening. If you touch the bump and it is hard that's usually a good indicator hes backed up. Coco fibre is probably the safest substrate to use.
