Spiderpig guide
Spiderpig is a Cosmic with an unusually high income for its rarity: $25M/s puts it in a tie for 3rd of 28 Cosmic pets. It's the second-lowest earner of the Unstable Egg, the pool tied to the Unstable DNA banner in Dr. Scramble's Laboratory.
A swap that roughly breaks even
Unstable DNA is the Laboratory banner that reaches furthest up the biome list. It draws from Cosmic, Cherry Blossom, Titan Temple and Angels & Demons eggs, and among the Angels & Demons pets it accepts are four Cosmics: Imp and Sacred Moth ($16M/s), and Demon Hound and Holy Peacock ($25M/s).
That means a Spiderpig earns exactly what a Demon Hound or Holy Peacock does. If you hand one of those to the banner and the egg gives back a Spiderpig, your income stays the same; trading an Imp or Sacred Moth for one is a gain of $9M/s. Update 6, which introduced the Laboratory in place of the Rift Trade-In Machine, also lets you trade eggs directly and made pity guarantee the top reward.
The Unstable Egg's other pets

- Spiderpig, Cosmic, $25M/s
- Sharkodile, Secret, $350M/s

What mutations and weight would add
Base weight is 180 kg. Estimates using the formula the wiki documents:
- Golden: about $62.5M/s
- Rainbow: about $87.5M/s
- 10x base weight: about $103M/s
- 100x base weight: about $428M/s
- 200x base weight: about $592M/s
- Rainbow at 100x weight: about $1.5B/s
A Scrambled Mutation from the Experiment Shop (x2.75, 10% chance per use) would bring a plain Spiderpig to about $68.8M/s. A 100x copy would clear a plain Sharkodile.
