I mentioned finding some old slides, there was not much there, but will post what was.

Ari jumping through the fire hoop
The group situp, same line up as before
Bagheera sitting up on Joyce
Bagheera jumping through fire hoop of which there were three, and as Joyce ran around, Bagheera jumped.
Bagheera sitting up on the mirrored "pyramid" In regards to the question who picked up Ika and Ari, and how old were they, Margaret and I seem to recall Herta picking them up, and bringing them to Marineland. John Cuneo doesn't remember, and Herta doesn't remember who picked them up, but say's it wasn't she. So there you have it.
