I just recently finished the Dark Talent and wow was not what I was expecting.
Anyway I’ve had this thought since book three that Alcatraz might not be able to become a popsicle, but he could look like one if he wished.
In book one he has his famous popsicle speech and then in book 2 he is jealous that Australia can look like a popsicle for a short time in the mornings. In book 4 he mentions that just hoping doesn’t get you anything, otherwise he would be a popsicle (see book 1).
Anyway, while reading book 3 he had the perfect opportunity to bring up the popsicle and he didn’t. I’m so disappointed in him. When he was given the disguiser lenses, I was fully expecting to ask if he would turn into a popsicle, but no he asks about a boring rock.
Despite that he didn’t say anything I assume that he uses the lenses to look like a popsicle (with glasses).
