Looks like the yacht is underwater? the swamp creature looks like it has its grip on it.
Level 325... glass moves level with lock & chain, crates, and walls.
so i've managed to get through this entire region, but still stuck on the last level of it within these past couple days. and i notice for this region the theme seems to be lock & chain. it's a feature in all of the levels except for one. level 325 only has 4JC, so making matches wasn't too terrible. each lock has a count of 36, and only 35 moves to pass the level, so try to make matches that will result in extra matches per move.
i'll post the rest of the levels later... so tired now
