|Turns out that weird locked door needed a special skull key, found by setting the eyeball statues into a specific pattern...|
Anyway, I got the mermaid transformation, beat the incredibly easy labyrinth boss, and then explored the water areas and found 3 golden squid babies... The next story part was at the lighthouse, where Sky and Bolo said that Mimic got captured by Risky, then the squid from the first level came and said he'll tell me how to get into Risky's hideout if I could find his 3 babies, which I already did...
After exploring everything, I was left with only 3 magic jams missing... I checked a guide to confirm there was 1 in the first labyrinth, 1 in the 2nd labyrinth, and 1 for beating the battle tower a 2nd time. the battle tower was actually very easy this time around.
Now I've found everything there is to get in this game, and the only thing left is to go to Risky's hideout and beat it... I'm not expecting much honestly... Overall I was very underwhelmed by this game... it seemed promising at first but at the end it feels very unfinished.
