Jo-Anna,
I think your frogs are being modest!! In each picture they have their privates...private! The new Elton looks like he's wearing a moss figleaf!LOL
I don't know enough or have the experience to help you, but I just love their cute little underbellies and I do the gitchy, gitchy, goo to them when mine are on the glass and I can see their bellies.
It's so wrong and I look so rediculous, but I can't help myself!!LOL
