Images and description of some of the wacky gadgets you see in the anime ^^ I'll list them by the order they show up in the series.

	PEARL DETECTOR A handy little tool that Hippo uses to spot the pearls when they were lost. It is useful to track down the mermaid princesses as well, since they carry the pearls ^^
	PEARL LOCKET Very important to mermaid princesses, because they use their respective pearl locket to transform! The pearl is located inside it, and each mermaid princess has a locket of their own representative colour.
	MICROPHONE I don't think there is an official name for it ^^;; It's not called "E-pitch" because E-pitch is a name for the MMPPP mic toy as part of the "E-kara" line. Obviously, the microphone is the Pearl Voices' weapon, transformed from their Mermaid Pearls. They sing into it to defeat the villains ^^. Click here to see the new style of microphone given by Aqua Regina in the later episodes.
	BUBBLE MAKER The mermaids' bath toy to be exact ^^; Turn the handle clockwise, and bubbles will come out automatically! Wheee...no more expensive foam bath =P
	MUSIC BOX Nothing really special, just a rotating music box with a pearl in the middle, and it plays the opening song of the series ^^ In episode one, Lucia sleeps with it turned on, so I guess the music helps the mermaids go to sleep? I'm not too sure ^^;
	MERMAID FORTUNE TELLING CARDS Pretty accurate cards to predict the future, introduced by Hanon. First you think about the person whose fortune is bring predicted while shuffling the cards (You can do it on yourself too). Then you line up 3 cards and put one more card above the middle one. The card in the middle represents the personality of the person. To see love compatibility with another person, arrange the cards so that 3 cards goes onto the top row and 4 on the bottom. These card combination will tell you how your love life turns out, as well as your lucky item.
	FRIENDSHIP RINGS They are not magical items, but accessories made by Lucia for Hanon and Lina as a symbol of friendship. The green one is for Lina, blue for Hanon, and pink for herself. When Lucia first made this she was afraid Lina won't accept it because Lina was rude at the time.
	DOKI DOKI STONE Madame Taki's magical fortune telling item, something that works for once! This stone will make people say whatever is in their mind, according to the temperature of the environment the stone is in. If it is in a hot place, the owner becomes happy; if it is in a cold place, the owner becomes all depressed =( In the most extreme case if it BREAKS in a cold place and continues to freeze, the owner's mood will fluctuate from one extreme to another like a drunkard xD And this is exactly what Lucia did when she takes care of Kaito's cold...see episode 23! :P
	MERMAID BEAD It appeared in episode 37, when an old lady accidentially dropped it and it ended up in Lucia's school. All the girls go scrambling to find it when Lina told Lucia and Hanon (when the PA system was on) about its romantic legend about how it was given to a girl by a mermaid, who revived her lover in a coma and so they got married. The old lady turned out to be the girl in the legend, but the ending wasn't was it's like in the legend because the guy left her after he woke up =(
	YUMEMISEKI Translates as "Dream Seeing Stone". Found by Lucia on the beach, it has the ability to make dreams come into reality! Of course, Lucia had to use it, hoping to make her wonderful "rabu rabu" dreams with Kaito come alive. And of course, thing did not turn out nicely as she thought...instead of a good dream, she had a nightmare abouu Kaito getting mad at her; and with this the usual Lucia-paranoia induced drama began xD; One good thing that came out of this is we now know Lina's lifelong lust is for a Plasma TV ;)
	FUUIN NO KAGI (SEALING KEY) We first see this key when Sara gave it to Tarou as an invitation to Gaitou's castle. Back in the day when Aqua Regina defeated the Sea Monsters, she used the key to seal the evil inside the castle, which the evil Sara released when she obtained it later. It is the sole key to enter the castle from the entrance, and its power can prevent ordinary humans from drowning underwater. When Hippo got hold of it he transformed into a water pegasus and broke the Black Beauty Sisters' song =)
	BLACK BEAUTY SISTERS' MICROPHONES The mics that the Black Beauty Sisters use to sing their songs, attached to their tails. They are not as fancy looking as the mermaid princesses' though xD; There is a hole on the side to put a pearl in, through which the Black Beauty Sisters gain power.
