In Star vs. the Forces of Evil, River Butterfly survives a fall that left a huge crater. I'll be calculating his durability.
Star Butterfly's Height = 1.60 m
Crater Depth = 2.96 m
Tree trunk width = 30 cm (Apparently there is no standard width for tree trunks, so I just measured an average tree near my house)
Crater Miameter (Minimum) = 9.91 m
Crater Radius = 9.91/2 = 4.955 m
We put these values on this Ellipsoid Calculator and then halve the result to get the volume of a half-ellipsoid.
Volume = 304.42/2 = 152.21 m^3 or 152210000 cm^3
Pulverization of rock is 214.35 j/cc (The trees being there is likely a drawing inconsistency, since the crater is almost 3 meters deep).
Energy = 152210000 x 214.35 = 32626213500 Joules
River Butterfly's Durability = 7.80 Tons of TNT (Large Building level+)
