What else should be added to owl carry list?

[celeste5000]

my ideas:

objects:
-switch
-button (upside-down)
-key
-bonusblock + infoblock
-dispenser
-powerup (egg, star, etc)
-fallingplatform

badguys:
-owl
-mrsnowball, mrssnowball, captainsnowball, bouncingsnowball, snowman
-haywire, divemine, shortfuse
-igel
-toad
-totem
-crystallo + sleepingcrystallo
-spiky + sleepingspiky
-jumpy
-viciousivy + walkingleaf
-tarantula
-mrtree + stumpy
-stalactite + mole's rock

i believe at least some of these would open up more potential and expand into a variety of uses for the owl.
