What is the name of this toy?

I can't seem to remember the name of this particular toy I had while growing up. From what I remember it was like a plastic pendant kind of thing shaped as a flower and you could open it (there was a lid), and in the centre there would be this sort of gel/jelly and you could grow a small sprout in it. The pendant can be compared to a small lip balm container (the kind that has a screw on lid), and it hung on a cheap string with a snap closure. Overall the toy had a pastel-y colour theme about it. And the gel was yellowish (sort of like hair gel). If it helps, I grew up in the 90s. Thanks in advance!
