I asked my SA about Rooroo. Are they rarer than a Rodeo to find? This is my first Rodeo that my SA was able to get for me. I'd like to get a Rooroo one day.
Yeah they definitely come in batches I think. They had probably 6-8 in stock in Harrods when I got mine. I asked to see five of them, and I got a pic of three of them here.
Pain d’epice, bleu de Malte, rose Azalee
Noir, bleu de Malte
Sesame, craie

Off the top of my head, the others included -
Noir, bleu de Malte, bleu de Malte (stripes and strap)
Feu, rose azalee
Lime, bleu Celeste (I think!)
Hope this helps.
