It wasn’t actually a toad. It was an African Clawed Frog (Xenopus laevis). For some reason, it was referred to as a toad in the school in which it lived and I worked. It had a metabolic condition that meant that its cells took in water osmotically. As a result, it was almost spherical in shape. The sixth form Biology students and I had a ritual in which we would use a syringe to extract a cubic centimetre of fluid from the toad each day. It didn’t seem to mind but I am not sure that it made any difference to its condition.
