Hi!
Just in case you didn't notice this earlier
Could you please add the bento av a full body size parameter/variable? That would make avatar size change much easier. I especially expect if it could increase/decrease the size till target value like this:
Three variables: size, growth/shrinkth speed and target size
If target size < size
subtract growth/shrinkth speed from size (or set size=size-growth/shrinkth speed)
If target size > size
add growth/shrinkth speed to size (or set size=size+growth/shrinkth speed)
So the growth/shrinkth would be smooth and noticeable instead of instant
