I looked it up and noticed that it is obtainable with a tentacular potion that was given out during a meet up. I have heard several people say that you can get it through zapping or experimental dew, and I can confidently say i've gotten every single experiment at least once except 333. Has anyone gotten it this way or am i wasting lots of money??

if you can get it then I guess i'll keep spending and hoping...!

all experiments can be obtained by zapping and through the potion. sometimes it just feels like it takes forever.

I have gotten this color through zapping.

Yup the dew can give you one. Sometimes the dew is nice and sometimes it hates you. My personal record has been 88 zaps and dews to get the experiment I wanted.

Thank you all for the reassurance. I'll definitely keep at it!
