I bought just one 3 pack got a subterra Mega brontes, ventus brontes and a blue translucent spindel (I guess this is the "aquos glow") the blue is different from the neon aquos brontes that I have, this one is much darker. And no it doesn't look like it glows in the dark.
Sounds like a regular Translucent Blue to me... nothing to do with the "BakuGlow"... we've already been told Translucents are the specials in the new BakuSphere type tins.. so I wouldn't rule it out based form your descrip. They seem to be pretty random as they were the first special types. Liek the Trans Pyrus Centipoid and Aquos Oberus from Bakuswap.Crappy Aquos Comparison:
Normal, Translucent, Neon, Pearl, Reverse/Flip
