Robin befriends Annie, an amnesiac girl with a dark secret.

----
!!Tropes:
* AbusiveParents: Annie says that she's running from a man who's always following her. He claims to be her father, and beats up Robin and Batman to get to her. Given Clayface created her, he's not far from the truth.
* ActuallyPrettyFunny: Annie giggles when Robin remarks on how she doesn't remember anything, after she said he was the first person she could remember showing kindness.
* AdultFear: Robin while searching for Annie comes across multiple homeless kids and runaways.
* {{Animesque}}: A little more so than Creator/{{TMS|Entertainment}}'s other episodes, with the look and feel of it in particular more closely resembling that of Creator/StudioGhibli.[[note]]If one chooses to take a look, the end credits ''does'' confirm the company's use with its animation director ([[http://www.animenewsnetwork.com/encyclopedia/people.php?id=1721 Hideaki Yoshio]]) and some of the key animators ([[http://www.animenewsnetwork.com/encyclopedia/people.php?id=1719 Atsuko Otani]], [[http://www.animenewsnetwork.com/encyclopedia/people.php?id=1729 Mariko Matsuo]], [[http://www.animenewsnetwork.com/encyclopedia/people.php?id=1720 Takeshi Inamura]] and [[http://www.animenewsnetwork.com/encyclopedia/people.php?id=1725 Eiji Yamamori]]).[[/note]]
* AntiVillain: Clayface, but to a lesser extent than in "Feat of Clay" and "Mudslide". Considering he didn't think Annie was real, he logically wouldn't see anything wrong with reabsorbing her.
* BigOMG: When Batman discovers what the mud was.
* BreakTheCutie: Happens to Tim Drake after Clayface absorbs Annie, causing Tim to brutally attack Clayface.
* CallingTheOldManOut: Robin calls out Batman for not caring about Annie's safety when she's alone, in trouble, and scared.
* DownerEnding: Annie dies, being reabsorbed into Clayface.
-->'''Batman:''' Sometimes, there are no happy endings.
* TheDulcineaEffect: Annie inspires this in Tim.
* GPSEvidence: A little more justifiable here: Batman still took a random mud sample, but rather than discovering an obscure location from which it came, he instead discovered that it was part of Clayface... and he's unique.
* HeroicSacrifice: Annie let herself be absorbed to save Robin.
* HiddenEyes: Annie has them as soon as she realizes she's a part of Clayface.
* LineOfSightName: Robin names Annie after seeing a girl holding a BrandX version of a Literature/RaggedyAnn doll.
* NotSoDifferent: Robin tells Annie that he's helping her because he was also a runaway and had a dad who wasn't a prize either.
* PunchPunchPunchUhOh: Batman and Robin encounter this problem when fighting the girl's "father".
* OhCrap:
** Annie when a motorcycle gang corners her.
** Batman when he realizes who "Daddy" is.
** Robin when he sees Annie's father melt into Clayface.
** Robin when Clayface overpowers him and prepares to drop him into a vat of acid.
* {{Shotacon}}: Annie doesn't look much older than Robin, and is in fact ''much'' younger, but that doesn't stop a motorcycle gang from cornering her.
* ShoutOut: Annie looks like a young Natalie Portman in ''Film/TheProfessional''.
* TheUnfettered: After Clayface absorbs Annie, Robin nearly kills the villain by pouring chemicals on him. Batman has to restrain him from delivering the final blow.
* WhamShot:
** The man dissolving into Clayface
** Annie's skin absorbing the clay that falls on her hands.
* WhatMeasureIsANonHuman: Annie after she remembers the truth doesn't believe she's real; neither does Clayface. Robin begs to differ, trying to protect her to the bitter end.
