It's hard to picture the yellowish blobs to which you're referring. As you may know, snakes can store sperm for years, so I wouldn't want to rule out jelly beans (AKA slugs) right away. If the temp is too high, it can increase activity levels and can also affect parturition (the birthing process). Double-check that first. Then could you give a bit more detail about the "blobs" (i.e. size, composition, when you first noticed them and how often they occur). A picture might also help (
Posting Pictures).
