So the gardener came over earlier today and found what I suspect might be mum's "mystery toad". We're still at a bit of an impasse as to what we should name it and have narrowed it down to
Puggle (Ray's suggestion)
Big Momma (Mum's suggestion)
Yo Momma (My suggestion)

Latest update: We have released Puggle back into the garden as of yesterday night! I daresay he enjoyed his time while he was here but a wild toad should always be allowed to do what a wild toad does best! Hop about to its heart's content! I will always be leaving out a dish of worms for him every night though! Perhaps one day I shall see him again. (4/3/2013)
