King nuzzles Marik's hand and makes happy Goomy noises, gladly gathering some leeks in its mouth! See, he can be helpful too!

As for Kaiba...well, he'll be carefully twisting and tying his ruined (and washed) turtleneck into an extra bag for leek carrying. He gathers the few on the bank, then looks up at Marik.

"...You might want to wash your face. But don't do it downstream from King."
