Madame Webria is the fourth boss in Astro Bot Rescue Mission. She makes a cameo appearance halfway through world 4-4 where she can be seen crawling up the wall and out of sight on the left side of the screen. She makes a full appearance as the boss in World 4-5, Swingin' Sister.
Appearance[]

Madame Webria on a cave wall.
She is a giant spider with light purple skin and small black beady eyes. She wears a vest like girdle with a heart on the back, red lipstick, a magenta high coiled long curly tea party Rococo Lolita hair style wig and some high tech dragon fruit shaped glasses. The spider also has an underbelly with heart patterns that resembles a pair of heart boxers.
Walkthrough[]
After you rescue enough bots to unlock world 4-5 Swingin' Sister, the level starts with Astro Bot moving throughout a small cave before eventually coming a giant room. Once you step onto the big platform in the center of the room, the path behind you collapses leaving you trapped in the room. Suddenly, a pink glow lights up the room, and the spider crawls up the wall, swings down & laughs, beginning the fight.
Boss Fight[]
The boss has 2 attacks:
Attack 1: She tosses down a bunch of eggs which hatch into baby spiders which Astro must punch away
Attack 2: Hanging off the back wall of the cave by web strands and spitting purple goop at Astro
When she latches onto the back wall of the cave, the web strands holding her up glow yellow on certain parts. Using the shuriken gadget, the player can cut the web strands and force her to stop attacking. She will hold on to the ceiling after the web strands on the wall are cut, requiring the player to cut the ceiling strand to knock the spider down. When she is knocked down, the player must have Astro punch the spider's cheek until it turns bright pink, and causes the spider to fall off the platform and into the abyss below, only for her to crawl back up the wall for another round.
Repeat this 2 more times (while being careful not to fall off the platform, as it gets smaller with each hit to the spider, and also to free Astro when the spider grabs him in a web before she throws him off the platform), until eventually, the spider's shades and lipstick break, forcing her to hang on the ceiling from unbreakable webs. To finish her off, you must, no joke, use the shuriken gadget to cut off the strands on the spider's vest girdle busting it open. Once this is done, the spider, in shock, will cover up her exposed boxer shorts with pink hearts on them with all her legs and wig looking embarrassed. This proves to be a mistake and she plummets into the abyss below for good, the pink lights fade and the fight ends. Defeating her also rewards the player with the "Heartbreak" Trophy, as suggested as her clothes were torn off revealing her heart patterned boxers.
