Kelp: Offshore Offspring has drawn more than 2,900 Gamefound backers, but existing owners do not need another base-game box. Wonderbow’s campaign sells its two new expansions together for €44; newcomers can instead buy the €60 Deluxe base game or the €126 gameplay bundle.
Our November 10 check of the official campaign showed €303,598 pledged by 2,911 backers against an €8,000 goal. That is a dated crowdfunding snapshot, not delivered sales or a verdict on the expansion. Wonderbow’s own shop also advertises the campaign as live.
The offspring change the duel
Kelp pits a shark against an octopus. Offshore Offspring introduces their young: Wonderbow describes sharks hunting as a pack and octopuses growing and using camouflage to survive. The official first-look video above shows the publisher’s pitch, not an independent playtest. GameGuideDog has not played the expansion.
The smaller Amazing Adaptations adds optional Adapt Cards for the Octopus and Bite Tokens for the Shark. In its September 25 update, Wonderbow says players can use either module or both. A separate publisher reply confirms that the two new expansions work independently with the base game. Buying Offshore Offspring is therefore not a prerequisite for trying Amazing Adaptations.

Match the pledge to the box you own
The €44 reward is the obvious starting point for owners who want both new expansions. Offshore Offspring is also listed separately at €35, and Amazing Adaptations at €9. The base game is required; the expansion bundle is not a standalone €44 entry into Kelp.
For newcomers, €60 buys the Deluxe base game, while €126 buys the Deluxe base plus all expansions. The €194 Deluxe All In adds accessories. That €68 difference buys the accessory package rather than more gameplay expansions. Even the all-in description excludes the follower-gift wooden tokens and alternative urea blocks, which are separate add-ons. Check the actual contents instead of reading “all in” as literally everything.

The pledge price is not the final bill
Shipping is charged later in the pledge manager and depends on weight. Wonderbow says EU VAT is included, while applicable US sales tax and any tariffs at fulfillment are extra; Canadian GST/HST is also added later. Check your region’s terms and current delivery estimate before backing. Production and shipping can slip.
