Return to the Spider-Verse: Part 2

When Spider-Man and Kid Arachnid were sent to recover the shards of the destroyed Siege Perilous, they enter into the Vampire Universe before heading to the Pirate Universe. They encounter Web Beard until they are attacked by the crew who demand the treasure. In order to get the shard, Spider-Man chooses to surrender much to Web Beard and Kid Arachnid's shock but he believes that Dread Pirate Duck is more reasonable than Web Beard. However, they are tied up and are about to be fed to the Kraken. Web Beard believes "Coco" will save them until he sees the coconut in the water and believes it to have traitorously run away. Kid Arachnid uses his venom blast to free them but one of the ropes hits the Kraken in the eye causing it to attack the Groot. Cosmo fights Web Beard until Spider-Man and Kid Arachnid manage to reason with them to work together with Dread Pirate Duck agreeing. The Spiders and the pirate are able to defeat the Kraken by tying it up and it leaves. Web Beard is glad to have his crew back but Dread Pirate Duck tells him that they maybe back but they all get a vote. Spider-Man and Kid Arachnid leave for the next universe.
