Project A spawns 6 seconds after the stage starts along with one Dolphina. Another Dolphina will spawn 30 seconds later. Roughly 44 seconds later, a Dolphina will spawn. 3 more Dolphinas will spawn in 20 second intervals. There are only 6 Dolphinas in this stage.
Shibalien Elites are spawned in mild intervals starting 30 seconds in.
A possible strategy is to only spam buffed Rover cats (with high level and combos to improve their stats further) and time the cannon to allow the dolphinas to stack, you will also need someone to outrange everyone, the idea is that the dolphinas never hit the enemy they target, as they are always in blind spot, while project a will have an hard time with the rovers who are tanky and resist warp. Frequent help from A. Bahamut is recommended. This strategy is partially luck-based, as getting rovers in place isn't easy. (speed up combos may help).
