A fairly common staple of Western Animation, this trope involves a character being so enamoured with another, their whole body turns into a puddle of goo. Can be used as the female equivalent of Something Else Also Rises (and often is, as seen in a lot of Warner Brothers 1990s cartoons, like Animaniacs and Tiny Toon Adventures). Male characters can experience this too, but it's either used as a Censor Decoy if the censors don't want implications of erections to be shown or if the writer wants to move past metaphorically showing an erection or ejaculation and go straight to metaphorically showing an orgasm/post-coital come-down. A Sub-Trope of I'm Melting and a (sometimes) Distaff Counterpart of Something Else Also Rises.
- A Nemi strip shows the title character doing this while watching Khal Drogo, to her boyfriend's displeasure.
- Amélie, but here it represents heartbreak rather than lust.
- You could say that she dissolved into tears.
- Happens to animated Lizzie in The Lizzie McGuire Movie.
- This is how the Bizarre Alien Reproduction in Isaac Asimov's The Gods Themselves works - the three sexes literally melt into each other.
- Quite possibly the earliest example of this trope is the 1944 Looney Tunes short "Swooner Crooner", where the singing of a Frank Sinatra Expy rooster causes one hen to melt where she stands.
- In the 1956 Popeye cartoon "Parlez Vous Woo": When Popeye kisses her hand, Olive turns red, blows steam out of her ears, then melts into a thin flat Olive-Oyl-shaped puddle conforming to the contours of the staircase. Her comment: "I'm just like butter in your hand!" (Which sounds more like something Popeye would need if Olive weren't around....)
- Tiny Toon Adventures used this a lot. It happened to Buster Bunny in the Pilot, to Babs during the Christmas Special (After both were kissed by the other) and Plucky during the "Acme Bowl" and "Pluck Twacy" episodes (Both times after being fondled by an attractive female).
- Animaniacs also utilised this repeatedly. It happened to Dot (and some aliens) in "Space Probed" after their inner fantasies were projected on a screen, and to Minerva Mink in both of her focus episodes, after seeing Trudy's cousin/Werewolf Wilford (and to Wilford in "Moon Over Minerva", due to Minerva flirting with him).
- Played with in Ren and Stimpy. During a "Fantastic Voyage" Plot, Ren encounters and falls in love with a female bacterium. He collapses into a puddle after the first kiss... because she sucked out his skeleton.
- Rocko's Modern Life
- The titular character in the episode "S.W.A.K", after he learns that his crush doesn't have a boyfriend.
- He also pulls a variant when he melts with pleasure at the sight of a "sad crying clown in an iron lung" for sale, as he'd always wanted one.
- In the first half of the "Sludge King" two parter of The Twisted Tales of Felix the Cat, Felix does this when he sees Candy for the first time.
- Spliced: Happens to Patricia when she first sees Eduardo, during "Amazon."
- Captain Flamingo: Happened to Lizabeth in "Blindsided" when she heard Otto's "Suave Voice."
- Ed, Edd n Eddy: Happens to both Eddy and Kevin in "Pop Goes the Ed", when they first see Naz in her bikini.
- Teen Titans: In "Fractured", Larry does this after getting a hug from Starfire.
- Droopy, Master Detective: Happens to Rumpley in a Screwball Squirrel short called "A Screwball Romance," when he sees the cute poodle Fifi.
- Happened to Kellaway and Doyle after seeing Cookie BaBoom without her suicide belt bikini on The Mask: The Animated Series.
- Dexter the octopus did this once in Flipper And Lopaka, after being seduced by a jellyfish posing as an octopus.
- Happened to Casper in The Spooktacular New Adventures Of Casper episode "Poil Jammed" after Poil convinces him to help her be scary so Spooky will like her.
- In Groove High, Zoe melts into a puddle of water when Dom (Tom in disguise) compliments her.
- In the Sidekick episode "News at 11AM", Vana melts like wax when she first meets Allan Amazing.
- This happens to Charlie Horse in the Bob Clampett cartoon "It's a Grand Old Nag" after his Hollywood crush Hay-dy La Mare kisses him for saving her from a fire.
- The Wacky World of Tex Avery: In the Power Pooch segment "P.P. Loves Fifi," Power Pooch melts after the beautiful Fifi passes by. Though the actual melting happens offscreen, the puddle he becomes is seen after Fifi leaves.
- Used in a demonstrative sense in the Family Guy episode "Twelve Angry Men," Quagmire has his fellow jury members simulate the positions of an orgy. He then takes his position, "the butterpat," climbing on top of the pile and literally melting all over them.
