What are good mature animal companions in Pf2 for mount for casters? Int ones to be precise. No legacy content, and I'm playing halfling.
I was thinking about
>Elk
it's frightening, but it's 30ft movement and you need to be adjusted to enemy.
>Oozeform Chair
sound fun, but Im not sure how many times I'm going to grab something 15ft away. Especially when I have telekinetic hand. And it's slow. imprecise sense is a neat bonus
>Rootball Chair
Reach, 30ft movement, ignore difficult terrain and if I wish to invest more I will have leap with and glide
>Chetamog
40ft,ignore difficult terrain, sences, if I invest in it it will have climb
>Yzobu
40ft, and it has something similar to rising shield if enemy can smell it.

Any of them any good?
I will take any other recommendations.
