I’ve found some Spore creatures that are fat. Spore lets you make really fat creations easily with a very enlargeable spine, and a limb part that can be enlarged a lot. They’re mostly aliens because the main gameplay of Spore is about a creature turning from a cell into a space-faring species, but I think it still fits here.
For example, Sean1M made a lot of fat creatures. This is his old account’s creations, as shown in the Sporepedia. http://www.spore.com/sporepedia#qry=usr-Sean10M|500536784486
Here’s one of his creations, Starlight McNellit.
This is his new account’s creations. His account has been hacked so he has to post new creations here instead. http://www.spore.com/sporepedia#qry=usr-5poreMasterHi|500811993593%3Aview-newest
Here’s a generic search for fat as well. http://www.spore.com/sporepedia#qry=advasrch-Fat%3Afi-name%2Cauthor%2Ctags%2Cdescription%3Afu-CREATURE%2CTRIBE_CREATURE%2CCIV_CREATURE%2CSPACE_CREATURE%2CADVENTURE_CREATURE%3Afl-MOST_POPULAR
