The moment I stepped onto Firework Isle during the New Bloom Festival, I knew this wasn't just about beautiful outfits and dazzling fireworks. A mystery whispered through the island's breeze, centered around those enigmatic sealed cavern doors I first encountered during "The Wonderful Journey." Sure, the main quest had me unseal the Gloomy Cavern, but the real treasure hunt, the one that truly tests an explorer's spirit, was just beginning. It was a puzzle that required more than just a keen eye—it demanded deciphering ancient stone maps and hunting down elusive Launch Tubes scattered across the island's picturesque yet challenging landscape. The promise of hidden riches was too great to ignore, so I tightened the straps on my backpack and set out on what would become one of my most memorable adventures in Infinity Nikki.

My first task was to locate the three other hidden caverns. Thankfully, the stone map in front of the Gloomy Cavern served as my initial guide. The first one was a breeze to find, nestled directly north of the Songbreeze Highland Hillside Warp Spire. It felt almost like a warm-up. The real fun began with the second cavern. I had to journey to the eastern part of the island, to a majestic waterfall that fed into the waters northeast of Sparkheart Island. From the cliff top, I took a leap of faith, activating my Floating outfit ability to glide gracefully down into the misty veil of the waterfall. The entrance was hidden behind the cascading water, and inside, I was rewarded not just with the sight of the sealed door but also with a delightful Greedy Pouch full of extra Bling! The final cavern required a different approach. I warped to the Fireworks Peak Spire and began a controlled descent down the western coast. I had to be careful not to drift too far north to avoid a skirmish with some local Esselings. Following a trail of twinkling Bling and guiding lamps along the rocky shore eventually led me to the last hidden entrance.

With all three cavern doors located, the real puzzle commenced. Each door was sealed shut, requiring three specific Launch Tubes to be activated using my trusty Firey Glow ability outfit. The stone maps outside each cavern were my only clues, but let me tell you, they were masterpieces of cryptic cartography! The perspective of the mountains was particularly tricky to interpret.

Here’s a breakdown of my Launch Tube hunt:

• Cavern One's Launch Tubes: This set sent me on a scenic tour. I found one at the very peak of the peninsula overlooking the serene Clearheart Lake. Another was perched precariously on a cliff's edge south of a Warp Spire, slightly tucked behind some foliage but not truly hidden. The third required a trip to the southeast of the island's main dock.

• Cavern Two's Launch Tubes: This trio was a relief! They were all in relatively open, peaceful areas. One was on the shore southwest of Sparkheart Island, another south of a picturesque broken bridge near the Relic Isles, and the last was north of the vibrant hot air balloon fields. No combat, just pure exploration.

• Cavern Three's Launch Tubes: This final set was the most... let's say, engaging. The southernmost tube was guarded by a group of Esselings southeast of the Songbreeze Island Foothills Warp Spire. A few well-aimed Purifying Orbs later, the path was clear. The eastern tube was a platforming challenge, best approached with a daring jump from either the Crescent Shoal Warp Spire or from the Sparkheart Island side. Thankfully, the final tube of the entire hunt was a gift—conveniently close, completely unguarded, and sitting out in the open, as if the island itself was congratulating me on my persistence.

The moment I activated the last Launch Tube was magical. A resonant hum echoed across Firework Isle, and I watched as the final magical seal on the cavern door dissipated. Pushing open each heavy door felt immensely satisfying. Inside each cavern, a trove of treasure chests awaited! While each cavern held a different number of chests, the combined haul was nothing short of spectacular—a hefty bounty of gems that made every jump, puzzle, and minor skirmish completely worthwhile.

This treasure hunt was more than just a side activity; it embodied the spirit of discovery that makes exploring Infinity Nikki's world so captivating in 2025. It's one of the many intricate puzzles woven into the fabric of Firework Isle, a perfect example of how the game blends fashion, adventure, and brain-teasing exploration. With the ongoing New Bloom Festival and the wealth of content in the 1.2 update, us fans certainly have our hands full, but as this cavern quest proved, the rewards are always worth the effort. Now, if you'll excuse me, I have some new gems to spend on the latest festival fashion collection!
