Team Spidey are web swinging together in the city just as WEB-STER alerts them that Lizard is sneaking around the farmers' market. He sneaks in and steals things for his shrink potion recipe. It turns out, he uses it to steal everything. Team Spidey shows up and chases him. As soon as Spidey catches Lizard, his shrink potion flies up and shrinks them down to tiny size. Then a skateboarder splashes a puddle on them, which causes them to go down the sewers. Ghosty and Spin take the potion to WEB-Quarters and make a reversal potion. Spidey goes to the blue pipe to rescue Lizard, but when he tries to call Ghosty and Spin, his comm-link broke due to the slip and sliding. It's up to Spidey and Lizard to get back on land and get back to regular size. But Lizard also has to learn to work together with Spidey.

Team Spidey is having a good time going underwater in their vehicles until a baby dolphin comes by asking for their help. When they arrived at the trench, the baby dolphin's parents are acting weird and wearing dolphins-obey-me helmets and grabbing treasures in their mouths. It turns out, they're bringing Doc Ock the treasures inside a hidden cavern. It's up to Team Spidey and the baby dolphin to stop her and rescue the dolphin parents before she keeps the treasures forever as usual.

It's Earth Day. Peter, his aunt May, Gwen, and Miles are at the beach cleaning up trash and helping the environment. As soon as the beach is finally cleaned up and while aunt May gets ice cream for the kids, more trash comes to the beach. It turns out Green Goblin on his pirate ship is using his trash cannon to turn Earth Day into Garbage Day. The kids suit up as Team Spidey. The kids come up with a plan by using the surfers' surfboards by putting the web flags on them as boats. As they get to his ship, he traps them by activating closing doors by squishing them. It's up to Team Spidey to stop Gobby before he covers the whole city with trash and teach Gobby to help the environment.
