This can be done in Practice mode. Select Alisa and the Jungle Outpost map. There is a balcony in the starting area. Push your opponent to the balcony, then press Left + A to perform the Spinning Top to get the "Crushing Impact!" achievement. You will fall to the floor below. Repeat the same move on the vines at the side of the arena to destroy them and open a new path and get the "Please Don't Tell My Father" achievement.
