This custom took me longer than I figured it would.  Blob's base is a War Hulk (credit to Dimmu for the idea).  I sanded him down to get rid of the veins and Hulk's skin texture.  I used Plumber's Putty to "bulk" him up.  I used Kneaditite to sculpt his double chin.  His waistband, boots, and wristbands were all sculpted from Apoxie Sculpt.  Painting Blob took forever.  His arm and leg ball joints like to destroy paint jobs.  I had to use the super glue trick to get him to the point you could move him without killing the paint.
