I was going for one of the new Experiment 104 and I got the other one I wanted, 2759. dies
Come join me in "I got what I wanted from the Zapper but with the wrong pet!" complaining.

Is this not me.
This is exactly what happened with me and Belle (same experiments and everything XD), and I'm not sure if I should zap over it!
I know that too well. Like, a couple of days ago when I got the amazing pangosloth experiment and I was like "Nooooooooooooo~" because i was on a Pet that was supposed to be something "ugly". It hurt a lot to zap over it. sighs
Generally I seem to be more lucky with Experimental Dews than with any zapper there ever has been. points at Lili Took me 12 Dews but at least I finally got there.
Most of my pets are various lucky zaps, gained while I was trying to get the pet color achievements. I'd get the color I want, but not the species, or the species but the color was dreadful. Eventually I'd get some color/pet combo that I just adored and had to keep, and it was time to move onto another pet to be zapped. Thankfully now I don't have any colors to collect, so any zaps will be just for fun.
Big congrats to you for getting the experiment you wanted, sort of! grins
