This is a list of Rose Lalonde's possessions, excluding her outfits, computers, and weapons.
Eldritch princess[]
The eldritch princess doll
The eldritch princess was a pretty princess doll Mom gave Rose for her birthday. Rose believes this was a masterfully passive aggressive gesture. She later customized it with knit tentacles and a new head. Mom has refused to acknowledge it since then and it remains on the living room couch. The concept of a princess fits nicely with Mom's love of wizards and classical fantasy, but is in direct contrast with Rose's ideals. The eldritch princess possesses many parallels with John Egbert's harlequin doll.
Later, the doll became the tier two prototyping of Rose's sprite, Jaspersprite. Shortly after being prototyped with the doll, Jaspersprite uses the tentacles obtained from the princess to save Rose after she leapt over the waterfall to save her Cruxite item, the Cruxite Bottle

Magnetic Letter W[]
A whole set of Magnetic W's.
The Magnetic Letter W was one of a set of twelve magnetic W's that Mom purchased for Rose, after seeing that Rose had to stick two V's together to use as a W when spelling the word "shrew" on the fridge. The W's were bought "for [Rose's] convenience". Rose then wrote a letter of thanks, which was legally notarized and marked with blood.
After taking one of the W's, Rose replaced it with what she deemed to be its approximate value, 12 cents.
Rose once used a W as a fake moustache, though this served practically no purpose whatsoever besides being silly.
It was later combined with a bottle of her Mom's vodka to create the Magnetic Wodka.
Magnetic Wodka[]
The Magnetic Wodka was alchemized by Rose Lalonde by combining a bottle of Mom's vodka and a Magnetic Letter W. In addition to having high alcohol content, the liquid inside appears to have magnetic properties. So far Rose has never found a use for it, but it may have been used in her process of alchemizing her alchoholic beverages later in the game. It could also have been hinting at Eridan's quirk, where "v" in "vodka" would be replaced with a "vv", or perhaps the Polish name for vodka, wódka.
It cost 20 cobalt, 10 diamond, and 50 mercury grist.
Silken Wizardbeard Yarn[]
SILKEN WIZARDBEARD YARN (WITH MAGICAL PROPERTIES)
Silken Wizardbeard Yarn (with magical properties) was created by Rose during a spree of alchemizing things. She combines a wizard statue with a ball of purple yarn. The Silken Wizardbeard Yarn requires 100 cobalt, 200 amethyst, and 250 rubies to make.
The yarn shows up over 2000 pages later, when Rose uses it to knock out Dave Strider.
Telescope[]
Rose also has a telescope in her house's observatory. She used it to view meteors, as John did with his.
Velvet pillow[]
“You now wonder how to address the pillow situation. It seems the woman has you at a clear disadvantage.”
The velvet pillow is a plush purple pillow embellished with sewn-on buttons and trimmed with gold thread. It was first seen in Act 2 as a weapon of her mother's passive-aggressive ire (or, perhaps more realistically, a misplaced attempt at mother-daughter bonding) against Rose, whereupon she captchalogued it with the intent of later embroidering a poem in praise of motherhood in retort.
Rose vents her frustration on the pillow in Seer: Descend.
While this promise was never fulfilled, the pillow has made further appearances, first when Rose used it as an alchemy ingredient to create her Velvet Squiddleknit Dress . Later, she used it to express her frustration through the ancient and noble art of mashing one's face into soft pillows, first in Seer: Descend, and then multiple times during Act 6.
Later, Jasprosesprite^2 removes one of the pillow's buttons to serve as a placebo remedy for Tavrosprite's cat allergies. Whether the pillow used for this was from the pre- or post-retcon timeline is unknown. Indeed, it is patently unclear what happens to a person's sylladex items after they have died or been prototyped.
Jade Harley possesses a similar, green colored pillow, for use in conjunction with her crystal ball. Its relevance is probably minimal, although it could hint at the original purpose of Rose's pillow.
