Meet Ukulele...

I put my finger on Lola's back but I feel no vibration. So does that mean she is female?

That,I've never heard of. But pointy warts are said to be a sign of a female. I've never had anything to compare to, but Hans "Bug-Eye" is much softer than Greta or Uki or Banjo, and another FF member has made a similar if not the exact same comment about her male vs female toads. But again, with nothing to compare to, somewhat useless info.
Looking at the pics again, I don't see the bruise-colored throat of a male, not even the beginnings, just speckles. Banjo has the same sort of thing and I thought that meant she was a boy, but the vocal sack is higher up, and I think you'd see it.
Think you've got yourself a lovely little lady Lola there. Of course if she starts hollaring (singing) for a mate one night, that'll solve the whole thing right there.
