Walking with pig to gather truffles sucks because it's way slower than a horse so you need to keep waiting for it.
Make it keep up with you at least, it feels like those shitty escort missions where you walk faster than the npc and you need to stop so the npc can catch up with you.
Maybe also make some attention grab to let you know your pig found something (Who actually looks at the game while doing this shit), some kind of animation or sound idk (i know i can set alarms in ard, but truffles have like 5 models and i'm unsure if i got them all).
