Paper Mario: Sticker Star
In Paper Mario: Sticker Star, Shiny Goombas appear in three levels: the first two levels in World 4, and Bowser Jr.'s Flotilla. Unlike normal Goombas, Shiny Goombas battle in groups of three or more. Also, all stickers used against them (except for Thing Stickers) have their damage halved. Just like an ordinary Goomba, Shiny Goombas attack by headbonking Mario, but they spiral in the air before making contact making this headbonk attack much slower. A lot of coins are gained when the player defeats them, depending on how many there are in battle. Shiny Goombas also appear on top of snowballs from the Snow Spikes and if Mario hammers the snowball with the Shiny Goomba on it, Mario will have to battle it but if Mario fails to hammer the snowball with the Shiny Goomba on it, the player will have to start over at the bottom of the hill since Mario will be rolled over and take damage and even worse, the player will have to fight if Mario gets rolled down the hill and will be unable to get a Perfect Bonus. Shiny Goombas also appear in Whiteout Valley if the player uses a Jump type Sticker on a Shiny Paragoomba and if they still have HP left.
Mario & Luigi: Paper Jam
Shiny Goombas reappear in Mario & Luigi: Paper Jam as enemies. They are found in Sunbeam Plains and Neo Bowser Castle. They fight the same as a regular Paper Goomba but with higher stats. If defeated, they are guaranteed to drop either a Syrup Jar or a 1-Up Mushroom.
