Pooh, Simba, Timon, and Pumbaa's Adventures of Ice Age is another upcoming Winnie the Pooh/Lion King mixed crossover film planned to be made by Yakko Warner and Shadow101815. It will appear on Google Drive as part of a double feature with its preceding short Winnie the Pooh, Simba, Timon, Pumbaa, and Maggie Simpson in The Longest Daycare in the near future.
The film begins with a squirrel known as Scrat, who is trying to find a location to store his prized acorn. Eventually, as he tries to hide it, he causes an avalanche. He barely escapes, but finds himself stepped on by a herd of prehistoric animals. The animals are trying to avoid the ice age by migrating south. Sid, a clumsy sloth left behind by his family, and after meeting Winnie the Pooh, Bloom, Ash Ketchum, Littlefoot, SpongeBob SquarePants, Mickey, Charlie Barkin, Itchy, and their friends, is attacked by two Brontops whom he angered. Sid is soon saved by Manfred ("Manny"), an agitated mammoth who fights them off. Not wanting to be alone and unprotected, Sid and the others follow Manny. Meanwhile, Soto, the leader of a Smilodon pride (whom Carface, Killer, Ozzy, Strut, Ichy, Dil, Red Claw, Screech, Thud, Ursula, Plankton, and Team Rocket work for), wants revenge on a group of humans by eating the chief's son, Roshan, alive. There is an attack on the human camp, causing Roshan's mother to be separated from the rest when she falls over a waterfall. Soto's lieutenant, Diego (who is revealed to be an ancestor of Tigger), is sent to find and bring the baby back. Sid, Manny, Pooh, Bloom, Ash, Littlefoot, SpongeBob, Charlie, Itchy, and the others spot Roshan and his mother near the lake, having survived her trip over the waterfall. The mother only has enough strength to trust her baby to Manny before she disappears. After much persuasion by the sloth, they decide to return Roshan (nicknamed "Pinky") but when they get to the human camp, the humans are gone. They meet up with Diego, who convinces the pair to let him help by tracking the humans. The 14 travel on, with Diego secretly leading them to an ambush. Soon they reach a cave where Sid, Diego, Pooh, Bloom, Ash, Littlefoot, SpongeBob, Charlie, Itchy, and their friends learn about Manny's past and his previous interactions with the humans, where his wife and son were killed, leaving Manny a cynical loner. At the end of the film, Pooh, Piglet, Tigger, Rabbit, Eeyore, Kanga, Roo, Lumpy, The Vultures, Jiminy Cricket, Zazu, Kronk, Ash, Pikachu, Misty, Brock, Togepi, Littlefoot, Cera, Ducky, Petrie, Spike, Chomper, Ruby, Guido, Grandpa Longneck, Grandma Longneck, SpongeBob, Patrick, Squidward, Sandy, Mr. Krabs, Charlie, Itchy, Diego, Manny, and Sid battle Soto's pack and a short fight ensues. As Soto closes in for the kill on Manny, Diego leaps and stops Soto, who wounds Diego in the process. Manny, in vengeance, knocks Soto into a wall of rocks, where sharp icicles fall on Soto, killing him. Tigger blasts off Team Rocket, Mr. Krabs flicks Plankton back to his own time, Littlefoot and the gang use the fruits to scare away Rad Claw, Screech, and Thud, Ash orders Pikachu to use thunderbolt to blast off Ichy with Dil comeing back for him, and Ozzy, Strut, Ursula, Carface, and Killer make a break for it. Manny, Sid, Pooh, Bloom, Ash, Littlefoot, SpongeBob, Charlie, Itchy, and the others managed to return the baby to his tribe, and Diego rejoins them, as the group begins to head off to warmer climates.
