The Yakult Swallows announced that a new mascot will be replacing the departing Entaro. The new mascot does not have a name yet, so the organization is asking fans to submit suggestions.
Submissions will be accepted between May 5 and 23:59 on the 23rd. The fan (or multiple fans) that submits the winning name will be invited to the mascot unveiling ceremony.
