Springpetal Cave (ねじまく はなの どうくつ?) is the third main area of the Sparkling Labyrinth in Hey! Pikmin. It makes great use of the eponymous Springpetals. There are two main rooms in this area: both are large rooms with a Springpetal on the bottom floor, and with several floors higher up, made of branches, and with pathways to other sections of the area. The mechanic in these rooms involves the player getting as many Pikmin as they can in the bottom floor, then using the extra weight to jump to a higher floor, and using the Pikmin found there to jump even higher, or to continue forward.
In this area, the player is introduced to Springpetals, that are used to jump more or less high in the air, depending of how many Pikmin Olimar has with him. This area also contains many doorways. After making some progress in the level, the player can retrieve the first treasure, the Manifested Time Container. In order to do that, Olimar has to break a crystal with his Rock Pikmin, then spring to the treasure. Near the end of the level, there are some doorways making some kind of labyrinth. In the rooms on the other side, the player can find some Pikmin. The player needs at least 18 Pikmin, in order to use the Springpetal to jump high enough to get access of the Dutiful Watchdog. After that, the player can go to the end of the level.
Plants and fungi
From where Olimar lands, go down the two vines. Before going forward, you can use your jetpack to go through the fake wall and grab the six red Sparklium Seeds for a total of 30 Sparklium. If you want to be quick, you can also drop onto the second branch and walk off it, continuing to hold left until you reach the fake wall. After that, the Springpetal introduction cutscene will play, upon which the Pikmin will automatically grant you 4 Sparklium.
Continuing forward will bring you into a room with four multi-colored doorways, two of which are too high up for Olimar to directly access, with a Springpetal between them that, with the five Pikmin you should have now, won't yet take you to the branches above. Instead of going into one of the bottom two doorways, continue right – there should be another doorway. Through it is a room with two Grabbits and a Sparklium flower, and more importantly, two Rock Pikmin up the vine. Going out the exit will take you back to the room with four doorways, upon which you should go through one of them – it doesn't matter which, as both will lead to the same room, with a vine going down. Going down it will trigger a cutscene that will grant you four Rock Pikmin. Take the heart at the end of the room if you need it, then go back.
You should now have enough Pikmin that the Springpetal will take you to the second branch up – destroy the flower for 20 Sparklium, then go through the door. Two Rock Pikmin will be wandering atop a dirt block that requires at least 5 Pikmin on the Springpetal to destroy. Go through the red doorway, and then back on the central Springpetal, before dropping off onto the lower branch. To obtain the Manifested Time Container, clear away the Skutterchucks and go onto the platform up the vine, using the jetpack to fly over the crystal and to the treasure. Going up, there will be another Skutterchuck and a fake wall accessible using the jetpack from the ledge that hides 15 Sparklium.
Go up the vine until you see the bottom ledge. Now, go to the other side of the Springpetal, before going left to kill the Crystalline Crushblat. Pulling down the pulley will grant you 10 Sparklium, while going further left will present a crystal sealing away two Red Pikmin. Jump on the Springpetal, and go left from where you land. Entering the door will take you to a room with two more Red Pikmin that can only be accessed with a bomb rock. Eight Pikmin on the Springpetal will be enough to grab a bomb rock, and from there, throw four Pikmin – including the one holding the bomb rock – to the right side of the Springpetal; too far to the left, and you'll miss the rock. If you pull this off, your army should now be 16 strong. Go all the way back to the vine near the Springpetal room, and go to the top level. Going right will begin a cutscene that will end with you having 20 Pikmin – more than enough to go back to the Springpetal, jump on it, and reach the Dutiful Watchdog. Be careful, as you can only afford to lose two Pikmin while going towards this treasure. Now, go back down either of the vines on either side, landing you on a branch very close to the ship pod.
