After feeling Kizaru
Goofy was stuffing his face
Meanwhile he never did that with Kaido before going up the roof to face 2 Yonko
He only did that in Wano after he was knocked out and was drowing after barely learning new haki and being rookie with it so he needed to get his energy back
And also this was just nerfed Kizaru so he only felt little of kizaru's power
so he is saying Imu is stronger than
full all out Kaido and
barely trying nerfed Kizaru
