The thirty-first episode of the sixth season of Rugrats (1991).
The babies try to get Spike and Fluffy to fall in love with each other. Later, the families go to a Valentine's Day party, where Chuckie tries to give a Valentine card to Chas, who is alone.
This episode provides examples of:
- Abhorrent Admirer: When Phil is tasked with getting Chuckie another red crayon after eating the last one, he comes across a baby girl named Phoebe who has a crush on him. When he tries to get back to his friends, Phoebe follows him.
- All There in the Manual: Phoebe is never referred to by her name in the episode itself, neither when spoken to nor spoken about. Her name is listed in this episode's closing credits.
- Cats Hate Water: One of the babies attempts to get Spike and Fluffy to fall in love with each other is by taking them on a cruise (namely having them sit in a metal tub in Tommy's kiddie pool). When Fluffy is placed in the tub, the water terrifies her to the point where she rocks the tub and deflates the kiddie pool.
- Cupid's Arrow: When Phil and Lil fight over Cupid's arrow, they accidentally toss it into the air, and it lands on Spike. Angelica, who is dressed like Cupid, tells the babies that they need to find him a sweetheart, or else he'll have a broken heart. The babies try to get around this by being Spike's sweethearts, but Angelica tells them that they need to find an animal. Tommy gets the idea to have Fluffy be Spike's sweetheart.
- A Day in the Limelight: This episode's first act focuses primarily on Fluffy.
- Female Feline, Male Mutt: Spike and Fluffy, in that respective order. The babies trying to get them to fall in love with each other is what fuels the events of this episode's first act.
- Help, I'm Stuck!: When Chas accidentally locks his keys inside the car, the dads all get their elbows stuck in the partially-open car window and have to have them pulled out by a tow truck driver.
- Iris Out: This episode ends with a heart-shaped one on Chuckie's valentine to Chas.
- Joke of the Butt: Phil comments that the heart-shaped cookies look like butts. Much to Chuckie's horror.
- The Key Is Behind the Lock: In the B-plot of this episode's first act, Chas rents a car to go with his costume for the party. However, he accidentally leaves his keys in the car, which is locked, so the adults try unsuccessfully to unlock the car door.
- Love Triangle: Angelica and Susie each have a one-sided one with Timmy McNulty. They compete to see who can make him the better valentine, using their own materials. When the girls each give him their valentines, the thanks them for them, but rather than return their affections, he uses the materials from their valentines for his own picture of a fire engine, specifically, Angelica's shoelace for his fire engine's hose and Susie's button for his dalmatian's spot.
- Pair the Spares: Invoked; convinced that Spike needs a valentine, and no other animal being available (as Fifi had not yet debuted), the babies try to get him to fall in love with Fluffy. They don't get on well, until they both get splashed with punch and begin licking it off each other.
- Prompting Nudge: Lil does this to Phil when the latter struggles to decide who he should make a velentine for to get him to settle on her.
- Rule of Three: The babies try three attempts to get Spike and Fluffy to fall in love with each other. First, they try to get them to dance together, then, they serve them dinner. Finally, they take them on a cruise.
- Sticky Situation: Chuckie puts a lot of glue on his valentine to Chas, and when his head itches, his valentine gets stuck in his hair. Tommy helps him pull it out, which results in some of Chuckie's hair getting stuck to the valentine (which Chuckie thinks improved it).
- Toilet Humor: At the beginning of this episode's first act, when the babies are eating heart-shaped cookies, Phil asks Tommy, Chuckie, and Lil why they're eating cookies that look like their butts. Chuckie spits his cookie out upon hearing this, but Lil tells Phil that the cookies are shaped like hearts, much to Chuckie's relief.
- Trash Landing: When the Tommy pushes Chuckie in Dil's stroller towards Chas, Chuckie lands in the trash bag that Chas was about to dispose of.
- Valentine's Day Episode: This episode takes place on Valentine's Day.
