Sealed Gateway - Stage 1
This level is very straightforward but can be rough due to enemy presence. You will be faced by some Sword Soldiers from the get-go so quickly dash over to any one of the items, so you can use that to stun them then move in with the sword. Get all the items, defeat the Spear Soldiers the same way before using the bomb flowers to destroy the blocks in the way. The next section has more Spear Soldiers. Get rid of them too and refill hearts from the breakable pots and bushes.
Sealed Gateway - Stage 2
Here we have another very straightforward but rough level. First up in line is an encounter with the Chain Soldier. Damage it with sword from behind or the side once it throws the chain away from itself. In the next room are a bunch of enemies. Some use swords, others use spears and some throw bombs. Kill the ones on the ground first then stack your heroes to reach and kill the rest.
Sealed Gateway - Stage 3
Hit the orb so you can step onto the yellow blocks and hit it again to get over. Throw someone onto the other set of yellow blocks and have them activate the switch so you can proceed. The nearby treasure chest contains a purple rupee. Off to the left are some more yellow blocks, throw two people onto it, and toss a hero to the pair of treasure chests to score some more rupees and hearts. Back on the main area, pick up a bomb and set it by the yellow orb, run over to the pink blocks and wait for the orb to change colors. At this point, grab two guys and toss them on the switches so you can use the bridge. Continue onward to the gateway to complete the level.
Sealed Gateway - Stage 4
Use the elevator platform to go higher where you must gust jar two heroes over to a pair of switches, which controls the bridge. Defeat the monsters, and once you get to the next section, have your gust jar person stand on the green area while the other stack up. Now blow on the weights and use that to get the totem heroes across. Activate the switch here then boomerang the last character over. For the last bit of this stage, kill the two Chain Ball soldiers and you're done.
