  We employ three-dimensional numerical simulations to explore the impact
dynamics of non-spherical drops in a deep liquid pool by varying the aspect
ratios $(A_r)$ and Weber numbers $(\We)$. We observe that when a non-spherical
drop is gently placed on a liquid pool, it exhibits a partial coalescence
phenomenon and the emergence of a daughter droplet for $A_r>0.67$. In contrast
to the prolate $(A_r<1)$ and spherical drops $(A_r=1)$, an oblate $(A_r>1)$
drop with a high aspect ratio encapsulates air in a ring-like bubble within the
pool and emerges a liquid column that undergoes Rayleigh-Plateau capillary
instability, leading to the formation of two daughter droplets with complex
shapes. When the parent drop is impacted with finite velocity, our observations
indicate that increasing the Weber number leads to elevated crater heights on
the free surface for all aspect ratios. A prolate drop produces a less
pronounced wave swell and exhibits a prolonged impact duration owing to its
negligible impact area. Conversely, an oblate drop generates a much wider wave
swell than spherical and prolate drops. We analyze the relationship between rim
formation dynamics and the kinetic and surface energies of the system. Finally,
we establish an analogy by comparing the dynamics of a freely falling
non-spherical drop, undergoing topological oscillations during its descent from
a height, with the impact dynamics of parent drops of various shapes striking
the liquid surface with an equivalent velocity. Our investigation involving
non-spherical drops contrasts the extensive studies conducted by various
researchers on the impact of a parent spherical drop just above the free
surface of a liquid pool.
