@Luxary16 That is entirely possible, and of course none of these are meant to be seen by the player anyway as the characters never morph into those animations to begin with. I hope the fact that these animations look so bizarre when viewed in the debug mode can still be of interest!
Mario Golf: Toadstool Tour contains a debug mode in its files, which provides an animation viewer. For an unknown reason, the animations of the characters moving into their golfing positions have a variety of bizarre motions as part of their initial setup.
