Hardy Hound makes an appearance in EP053, in a description which Rubeus J makes to Venoct upon defeating him. Red J states Hardy Hound is far stronger to him and that he answers to him. Upon hearing this, Venoct states he will not lose and begins searching for Hardy Hound.
In EP064, he makes a cameo in "Kaptain Komasan's Expedition Team" to find the Yeti. Komasan unknowingly encounters him and mistakes him as the Yeti before exiting the warehouse. The final shot shows Hardy Hound eating what appears to be a large ice cream cone.
