|On the way through this forest area, there's a temple that has its door blocked off by monsters. After that there's Lilypad village. Some kid from this village was kidnapped by monsters, and the path to the right is just a very short dead-end path where you go to save that kid. That path has some kinda tough-ish monsters that are like hammer bros that move around more. I grinded here in order to by all the stuff in Lilypad's shops because it seems unlikely I'll ever need to come back here again...|
The kid that you saved turns out to be a helper that you can bring along with you. He smashes the door to that temple and allows you to get inside. This place is kind of like a Zelda 2 palace... the enemies here aren't very hard but there's a lot of them and they respawn a lot. I found a hidden room with a heart container thanks to the kid that is following me... and also found a chest with an elixer. I eventually found the way to the exit, but I think there were a few other paths I could've gone, so there might still be stuff in this place that I'm missing I dunno.
Hmm... that exit just leads back outside the temple where I came in... am I missing something important here? Well, I did get that lamp that lights up areas at least...
It turns out I was missing something important there.. instead of going through the door to the exit, I went down a pit and got to a new area with arrow shooting traps everywhere.. found a chest with a hard shield, and then found a switch puzzle where I just had to brute force the solution, and that opened the way to the boss... a couple of golems on two sides of the room. This boss was very easy... they shoot projectiles that can be jumped over from the platform in the middle or blocked with your shield.. and they have a very predictable pattern of rolling a boulder in and out of their mouth. it's just a matter of going in and hitting them a couple times when the boulder goes back in their mouth.
Got the trident, which according to an NPC is the item that is needed to swim in the ocean. Also beating that boss opened a tree stump doorway in Lilypad that is a shortcut back to Purapril village, so you don't need to go all the way down that forest path ever again.
