The Prestige Shop, in the same cave, has listed Trait Rerolls at 10 for 1 token and Magic Conches at 10 for 2 tokens, plus chest bundles and Shiny Wumbo units. SpongeHenge can also be bought there for 100 Prestige Tokens, or 250 for a Shiny Wumbo copy, after you have reached the tier. SpongeBoy is one of the Ultima shop units and is the accessible high-splash prismatic in endless discussions.

How to reach 100 again

Use a short story stage you can clear, then replay it. Conch Street 1 on Nightmare is the simple loop. Rock Bottom 1 on Davy Jones is faster only if your towers already win it. Daily and weekly quests add 50 to 1,500 XP.

Skip endless for account XP. It tracks waves and damage, not player level. Boss battles often pay about 5 to 39 XP. Raids pay more per clear and less per minute than a short story replay.

Stack 2x Player XP (979 Robux) with a 60-minute 2x potion from the merchant, season pass, or an old code only while you are actively clearing. Weekend admin events have applied much larger temporary XP multipliers. Those windows are announced, not on a fixed clock in this guide.

When can I redeem codes?

The code menu opens at player level 10. Before that, the box does not accept entries.

What do I keep when I prestige?

Prestige at level 100 is free. It resets your player level to 1 and keeps units, pets, gems, coins, items, and game passes.

Which tutorial unit should I pick?

Common SpongeBob, Patrick, and Squidward are starting choices for Conch Street. The published comparisons treat them as similar, so the pick does not decide your later account.
