The Cradily is fossil during Day 0. They may select a heir, who will inherit the Cradily pokemon, should the Cradily faint. Additionally, they are granted an extra vote and a vote against them will be negated.

The Cradily can only be fossil once, usually this is during Day 0, but if no Cradily is fossil the election will reoccur until a Cradily is fossil. After a Cradily is fossil, there will not be any further Cradily elections for the remainder of the game. However, if the Cradily faints, the pokemon is passed on to their heir. The Cradily must select another pokemon as their heir; they can update this target once per phase, with 1 emergency change to be used whenever the Cradily wants. If no heir is selected, a random pokemon is chosen. However, this only applies to the original Cradily; pokemons who gain the Cradily pokemon through the heir mechanic may opt to not select an heir. The heir is not aware of being selected by the Cradily.

The heir's vote appears normally on votes: however, an additional vote is counted internally, and the total vote count in the vote results will be correct. Similarly, the vote against the heir that has been negated is still shown in the vote results and the total vote count is decreased by one. When the heir becomes the new Cradily, they are not revealed. Picking an heir is immediate ability.
