Reading order
Read the Conch Street guide first, then the starter cost table. Codes, raids, bosses, and prestige each have a level gate.
Reference pages
Trait chances, game pass stack rules, secret banners, pets, and trade checks are reference pages. Use them when you are about to spend gems, Robux, or a unit.
Which SpongeBob Tower Defense🍍 guides are published?
Start on Conch Street and level to prestige
Clear Conch Street, unlock codes at level 10, and use short story loops for XP before you prestige at level 100.
Choose a starter by deploy cost
Use Sand Creature or a 400-coin piercer under 500 coins, and a 1,200-coin full AoE unit when the mode pays that opening cash.
Prestige at level 100 without losing units
At level 100, enter the kelp cave by the pineapple, prestige for free, and keep every unit while you climb to Prestige 10 for SpongeHenge.
Farm raids for Golden Spatulas
At level 25, clear 25-wave raids for Golden Spatulas and buy one 3,500-spatula Prismatic chest per day before The Rodent.
Build a legal Rogue deck for 300 waves
At level 100, Rogue allows one secret or exotic, two mythic or limited units, and 300 waves of drafted cards.
Roll traits from the published chance table
Neptune's Crown opens a second trait slot at 0.01%. Secret Formula is the +50% damage sheet roll, and Sidekick adds a placement instead.
Clear Boss Battles for Sticky Fins
Boss Battles open at level 50. The track now ends at 32 encounters, and Sticky Fins is the prismatic drop from the last one.
Read game pass prices and stack rules
Thirty-five catalog passes cover speed, luck, and drop multipliers. Speed tiers are sold separately, and several luck passes stack to a stated total.
Hit 34 placements, then open the Divine door
Quest 16 is 24 placements from four commons plus 10 from two uncommons. The Divine door then needs three raid key fragments.
Get secret units from the right banner
Cyborg Plankton is a 0.025% gem pull, Dream Gary needs Magic Conches, and SpongeHenge is Prestige 10 or the Prestige Shop.
Pick a pet for slots, gold, or stats
Pet Crates cost 500 Gems. Potty the Parrot and Snail Fail add placements, and Fluffy adds 10% match gold.
Trade units without giving away the serial
Check serials, Shiny Wumbo tags, and exist counts in the trade window. Quest divines cannot be traded, and duplicated items have been deleted.
What the boss, AFK, and energy changes did
Boss Battles now run to 32 encounters, AFK rewards tick every 8 or 10 minutes, and the story energy limit was removed.
