SpongeBob Tower Defense Values List — All 105 Items (July 2026)

Values in SpongeBob Tower Defense are unit-less community reference points, not fixed figures. Coins and Gems can never be placed in a trade, so there's no currency to quote a unit in — every value here is simply a read on how sought-after a unit is next to every other unit, drawn from how real trades tend to land. Because there's no official ranking, the numbers shift as the community trades, events rotate, and new units arrive.\n\nTwo forces shape where a unit sits. Rarity sets the baseline — a Common or Rare sits far below a Mythic, which sits below the Secret, Limited, and Exotic tiers at the top — and scarcity moves it from there. The rarest chest pulls and the event-exclusive Limiteds that can no longer be obtained hold their standing because supply is capped while interest keeps flowing, while a freshly released unit can ride a wave of hype and then settle once more copies are in circulation. Demand is the wildcard layered on top: a unit lots of traders actively want can outrank a technically rarer one nobody is chasing, which is why value lists group units into broad bands — Top, High, Mid, and Low — rather than pretending to precise figures.\n\nRead the ranking as relative standing, not a settled number. To judge whether a swap is fair, line up everything on each side, see which band each unit falls into, and check that the two sides land in the same neighborhood — a bulky pile of Low-tier units can still fall short of one Secret or Limited. Match the exact unit and rarity, since same-name units can differ, and factor in demand: a unit that ranks high but is hard to trade away counts for less in practice than a slightly lower one everyone wants. A trade is fair when both players are happy once they've checked it against the list — the value is a starting point for the conversation, never the last word.
