Will still have to actually verify some of those missing events, but from a quick look through the code:

• There might be no events yet for when a fox or panda picks up a nearby item.
  • EntityFox seem to override a(EntityItem), bypassing the general EntityPickupItemEvent already present inside EntityInsentient.a(EntityItem).
• Fox can pickup/eat berry bushes (EntityFox.f#m()). This might also require a EntityChangeBlockEvent.
