It's all coming together 
Just remembered one of Prince's jaunty little B-sides, "Horny Toad":-
Run, go tell your boyfriend his lovin' has got too old
He might as well pack his things
And get his dead ass on the road
Tell him you live on a lily pad
With a horny toad, whoa, yeah!
I expect Prince meant "horny" as in "randy", not "horny" as in "horned spikes" as in the case of the horned lizard which often gets called "horny toad".
