SOS from G.D. st. Jail

SOS from G.D. st. Jail was a collaboration event between Yokohama Hakkeijima Sea Paradise and JoJo's Bizarre Adventure Stone Ocean featuring new events and goods at the Sea Paradise Aquarium. It began on October 1 and ended on November 30 2022. For those who pre-purchased a ticket, a set that included a "one-day pass" and "Island Exploration Rally" admission received a original wristband with a prisoner's number (1 randomly given out of 9 types).

The story of the event involves the visitor being an agent of the Speedwagon Foundation disguising themselves as a prisoner of Green Dolphin Street Jail in order to infiltrate the facility and assist Jolyne and friends in finding Jotaro's memory DISC.

Summary
The event featured new activities and goods for visitors to enjoy. A stamp rally (1,300 yen per person) took place within the Aquarium where participants must complete missions in order to acquire stamps and keywords. If all stamps are collected and a participant reaches the end, they will receive a novelty DISC of Jotaro's memory. In addition, those who guess the secret card from the cards distributed as a goal bonus (1 randomly given out of 9 types) will receive a special acrylic stand to store Jotaro's DISC.

A special exhibit named "JoJo and Strange Creatures" was featured at the event. A large collection of "strange creatures" are featured in this exhibit including the Spotted Poison Dart Frog and the Barbados Giant Crab. The ecology and characteristics of the animals on display are presented with stand parameters such as "speed", "destructive power", and "precision movement".

The "Sea Animal Show" show has been altered to fit the event's theme. The new show premise has the Penguin's Memory DISC, which was scheduled to appear, having been stolen by Whitesnake. The trainers and animals then work together to search for the Memory DISC.

Art of the Stone Ocean cast appeared on the "Merry-Go-Round" attraction and "Dolphin Fantasy" in the aquarium. Additionally, at the "Carnival House" and "Western Game House", games related to Stone Ocean were featured. Customers who spent 500 yen or more on these event games received a random postcard (1 out of 4 types).
