you snuck your way right into my heart - phineas and ferb lyrics

i should’ve known
from how i felt
when we were together
and even more when we were apart
you tiptoed in
and you got under my skin
you snuck your way right into my heart

i put up barriers
to shield my emotions
a wall that you could never break apart
but like a ninja of love
repelling down from above
you snuck your way right into my heart
oh yeah
