Rolled 19 (1d20)
>>5597943Vee believes he is perfectly stealthy and hidden. That's why the monkey hasn't seen him.
He does a tactical roll on his side to reach thicker grass, just like Big Boss would have done in this situation.
Once he's in position, he tries to whistle (something he cannot do) to draw the attention of the Simisage, bringing him into concealment so Vee can knock him out without anyone seeing!
