Researchers in Habit City theorize that there may be new tools for managing tasks or even undiscovered creatures in these depths.<br><br>As you map rocky tunnels near the foothills of the Meandering Mountains, you notice a glow emanating from a craggy entrance ahead. As you near you see… toys? Stuffed animals and rubber balls are scattered around the cave floor. Is that barking you hear?<br><br>A huge, three-headed dog jumps out, darting for the toy you were right about to pick up! You freeze, almost losing a limb there! But... the dog’s mouths seem too occupied with toys to attack?<br><br>“Woof!” one of the dog's mouths barks, dropping a torn toy raccoon. “Are you here to help me clean?? I reeeally need to tidy up but every time I pick up a toy, I just end up playing with it… Here, think fast!!”<br><br>He launches a ball at you, and then another, and another. Those extra heads really make dodging a workout!",

Maybe next time try starting at the entrance and working backwards? Or doing it 30 minutes at a time with some short play breaks in between.”<br><br>“That’s a good idea,” the pup’s left head chimes in.

   "questFungiNotes": "It’s been a rainy spring in Habitica and the ground around the stables is spongy and damp. You notice quite a few mushrooms have appeared along the wooden stable walls and fences. There’s a fog hanging about, not quite letting the sun peek through, and it’s a bit dispiriting.<br><br>Out of the mist you see the outline of the April Fool, not at all his usual bouncy self.<br><br>”I’d hoped to bring you all some delightful Fungi Magic Hatching Potions so that you can keep your mushroom friends from my special day forever,” he says, his expression alarmingly unsmiling. “But this cold fog is really getting to me, it’s making me feel too tired and dismal to work my usual magic.”<br><br>“Oh no, sorry to hear that,” you say, noticing your own increasingly somber mood. “This fog is really making the day gloomy. I wonder where it came from…”<br><br>A low rumble sounds across the fields, and you see an outline emerging from the mist. You’re alarmed to see a gigantic and unhappy looking mushroom creature, and the mist appears to be emanating from it.<br><br>“Aha,” says the Fool, “I think this fungal fellow may be the source of our blues. Let’s see if we can summon a little cheer for our friend here and ourselves.”",
   "questFungiCompletion": "You and the April Fool look at each other with a sign of relief as the mushroom retreats to the forest.<br><br>“Ah,” the Fool exclaims, “that was quite a mycelial melancholy. I’m glad we could improve his mood, and ours too! I feel my energy coming back. Come with me and we’ll get those Fungi potions going together.”",
