I had my share of jelly and can honestly say that thinking I'm gonna save money by buying it instead of picking something silicone or even TPR is fooling myself. Jelly toys don't last. They yellow and loose their pretty colors. They also irritate some people's skin (the older the toy the more it leaks phthalates).
IMHO the only things that are both fantastic and jelly are gummi bears.
I may be biased but I would wait for a sale on silicone dildos and buy one and a small simple hard plastic clit vibe. This way you won't fall into the "wrong anatomy" trap that rabbits have. You can also look for something TPE/TPR (but it will still be porous = no way to disinfect) or silicone in the rabbit aisle.
