You'll find numerous items scattered around the horses.

At the "R1" block, push both toward the house on the left and use them to reach the roof. Follow the rooftops left to find 2 Stickers, as well as a Star Sticker Spot. Place the Star Sticker there (found in "Skate to Victory") to reveal 3 Objects. After the ramp, you'll find a Sticker, which you can then apply to a Sticker Spot just above that will reward you with 2 Stickers. You'll also find the second Star Sticker Spot here--place a Star Sticker there (located in "Skate to Victory") to reveal 3 Objects. Just after the first horse, look for the a Sticker in front of a tree. Push the second horse aside to find another Sticker, then check behind the tree just past the next obstacle for a third Sticker. After using the third horse to climb to a ledge above, leap off the far left of the half-pipe to grab a Sticker floating in air. After pushing the fourth hose down the long ramp, head left to find 3 Stickers by the base.

After crossing the murky waters marked by the Skull & Crossbones, grab the Sticker to the left of the first seesaw. Tilt the second seesaw so the right side is raised, and quickly leap off of it to grab the Sticker just above. Just after the second seesaw, you'll come across a stack of green boxes, with a Star Stick Spot above. Plant the star sticker there (located in "Skate to Victory") to unlock 5 Objects. Subsequently, leap from the green boxes to the trees on the left and follow them to find a 2 Stickers, then look for a second Sticker Spot on the cloud beyond. Plant a Star Sticker there (located in "Skate to Victory") to reveal 5 objects. Use the seesaw just before the flag to jump to the orange ball above, then swing to the key on the left, unlocking a Challenge. Just past the flag, you'll find a Tool as well as a Decoration.

Leap from the green boxes to the top of the tree for more goodies.

Place the Donkey Tail decoration anywhere on the Donkey, near the end of the level, to reveal 4 decorations. Halfway down the racetrack, look for a Sticker Spot. Place a Star Sticker there (located in "Skate to Victory") to reveal 5 Objects. When the Donkey comes to a rest against the large mushroom, leap from it to find a Sticker on the small mushroom to the left.
