Monster Family 2 (2021)

A young girl named Mila, who is part of the Starr family, infiltrates Count Dracula's castle, where the Wishbone family's old nemesis lives, to capture Dracula, who has been frozen by the latter family. The Starr family instructs Mila to capture Baba Yaga on her next mission.

The Wishbone family visits a wedding to witness Yaga and Renfield getting married. Mila arrives and kidnaps both witches. The Starr family then gives her a mission to capture Nessie, the Loch Ness Monster. Max, determined to save both witches, uses Yaga's magic amulet to transform his family into monsters, as before. The Wishbones reach Loch Ness, and during a fight with Mila, she manages to capture Nessie. As Mila returns to the surface, Max develops a relationship with Mila, but she leaves to go to a snow mountain to capture a yeti. The Wishbones follow her to the mountains, but Fay accidentally triggers an avalanche, which knocks Mila onto a cliff, being saved by Max. She then reluctantly sets out to Tora Tora to capture her final monster.

As the Wishbones reach Tora Tora, they befriend a giant gorilla named King Conga. Mila captures the gorilla and takes it back to the lab, where all the monsters are injected into a clone of herself dubbed Mila 2.0. Her family reveals that Mila is not part of her family, and Mila 2.0 is ordered to eliminate the original Mila. As she flees in tears, the Wishbone family arrive, and she shares what happened. Mila 2.0 captures and takes the group to the Starr family. The Wishbones are reverted to their normal forms. Max tries to shrink Mila 2.0 with a shrink gun, but ends up wrecking the headquarters, inadvertently shrinking the Starrs in the process. The Wishbones free the monsters in the ensuing destruction, while Max successfully shrinks Mila 2.0. Dracula also escapes, swearing revenge, only to be quickly shrunken by Max.

The headquarters begins to collapse, prompting the Wishbones and the monsters to flee. Mila frees Mila 2.0, but Max falls. While Mila rescues him, Mila 2.0 blinds the original Mila, leaving Max to give command to Mila's control. They successfully evade the collapsing headquarters, and they return to the surface. Yaga and Renfield are then successfully married, before imprisoning Dracula in a smaller version of his castle, and he enacts revenge against the Wishbones.
