And finally, #3. Thanks
looks like a miniature Gasteria (lilliputiana?)
Yes, Gasteria, don't know which, if not as above, maybe batesiana.
That's one nice plant. Never seen that one befor. It made my wish list.
You certainly can find one or two oddballs at the big box stores, It is like they hitched a ride with their more mundane cousins!
I also believe it's Gasteria liliputana.
