They both look like regular pastels to me. Lemon refers to a specific line of pastel and jungle is just the pattern. I wouldn't say either of them have a jungle pattern but that doesn't make them any less pastel.

$75 for a male sounds about right. they have been going for around $75-$100 lately.

Pastels can be bred with normals to get %50 pastel offspring or any other morph to get some cool combos.
