A very funny interpretation of the limitation, good introduction and well presented. In summary, I liked it :) As a suggestion (seeing that you are extending the game) maybe an evasive or defensive area move could work.

Could be a weapon that shoots in every direction (maybe just dashing rivals away, or killing them in a certain radius), with a relatively large cooldown. Or could be also a shield (some immune time, maybe?). In this way the player would gain some time when vegetables are about to take you. But these are just suggestions, of course ^^
