Facing a Headbutt tree asks to HEADBUTT it, and HEADBUTT from the party menu skips the question. ShakeHeadbuttTree shakes the tree as a sprite over grass, then TreeMonEncounter scores the facing tile against the trainer ID and draws from the map's common or rare tree table. A Pokémon that falls fights as BATTLETYPE_TREE: "fell out of the tree!", and the time of day's AsleepTreeMons species start asleep. Smashable rocks run SmashRockScript, and ROCK SMASH from the party menu acts on the facing rock; after the rock breaks, RockMonEncounter gives the map's rock set a 40% chance of a wild battle.
