Shiny Koopa Troopa
From the Super Mario Wiki, the Mario encyclopedia
Shiny Koopa Troopas are a rare species of Koopa Troopa that appear in Paper Mario: Sticker Star. They look like normal red or green Koopas, except that they shimmer, similar to shiny stickers. Shiny Koopa Troopa's only attack is going into its shell and hurling itself at Mario. Shiny Green Koopas can be encountered in battle normally and attack faster, but a Shiny Red Koopa can only be fought if a Shiny Paratroopa has lost its wings. Shiny Red Koopas are stronger than Shiny Green Koopas but Shiny Red Koopas act like normal Koopa Troopas.
