He does not say this in the Japanese dub.As a homage to his iconic slide sound effect from LINE Cookie Run and Cookie Run: OvenBreak, Herb Cookie will say 'Hoo hoo!' when sliding in running sections.
As with many plant-based Cookies, chopping wood causes Herb Cookie to frown.According to his loading screen trivia, 'When it gets too hot, Herb Cookie will bring in his plants and take a break from his daily walks.'.He's also shown to be a very kind and polite Cookie, calling the player an amazing friend and often being very generous to other Cookies. Herb Cookie is a plant lover through-and-through, treating his plants like how decent parents treat their children: when they have diseases, he will try his best to cure them, then bring them to an airy area while the weather is torrid.
