Whats the opposote of a piranha?

What’s that resting on the heads of the druids?

I’ll make sure I get to sleep,

Once I am done looking over my shoulder.

and cocking my head back,

but not with laughter

but not with sleep, either.

Kicking my legs, back and fourth.

Kicking

my

legs.

Those chattering teeth are right in my blind spot,

Just let me MERGE.
