The Straw Hat Pirates' Greatest Military Force
Gaimon's island was at sea-level: it's going to flood eventually, and soon.
Now that his Island is going to flood, Gaimon will be forced to relocate to higher ground, in order to survive, and save his Animal Frendos.
I believe we'll see Zoro's homeland, the Shimotsuki Village, have many people return to Wano, too:
A: Kaido's defeat is known worldwide
B: They heard the broadcast, and Koshiro expressed dismay at it:
Koshiro is a kind individual, and I doubt he would keep this info to himself: I've long suspected Koshiro knows more about the One Piece world than he's letting on, and has some awareness of the Dawn. Furthermore, while Koshiro was a big part of Zoro's flashback, we never saw how he met Zoro... his relationship with Zoro was portrayed through Kuina.
Zoro and Koshiro need to meet.
Koshiro will warn other East Blue Islands about the flooding, and try to take them to higher ground.
This will lead Koshiro to the Island of Strange Animals, and the strongest Marimo in One Piece, Gaimon-sama.
Gaimon and Sarfunkel will sail with Koshiro/the Shimtosuki Village people to Wano...
Where Tama and Gaimon will combine to form the Absolute Duo,
GAIM-O-TAMA
Gaimon, a fellow animal enthusiast, will become Kunoichi O-Tama-sama's right chest man, and help her handle her Merry and Merciless Menagerie
TAMA AND GAIMON, NATURE'S BEST FRENDS
I'm worried Gaimon can't join the crew because he's stronger than Zoro, tho, Zoro needs to get his power ups, and fast.
Gaimon rejected Luffy's request before...
But now, it's time for The Chest Beyond Abs to settle the score
