Animal miniatures?

[Vraille Darkfang]

For horses,

Look up mounted warriors. I got 2 Reaper figs mounted on horses. You can also take a unicorn & saw the horn off.

Reaper also has a bunch of dwarves riding bears.

One of my favorite animal minis is an old Ral-Partha Hippo my wife painted for me.

That's right a vicious war-hippo. Fear the War-Hippo! Worship the War-Hippo! Be the War Hippo!

If you're not dead set on minis, you might consider Fiery Dragon's Counter Collection 5: Summoned Creatures set, which includes every beastie on the lists for SM I-IX and SNA I-IX for $20. Their counters rock.

I was having the same problem with my sorcerer character, which had the Summon Monster spell. Then I started using D&D Miniatures, and they work pretty well. At each level of the spell, I picked the two monsters from each level of the spell which would be most useful in combat in most situations, and bought minis which could represent those monsters. It works out pretty well.

Now the player of our party's cleric, who also has the Summon Monster spell on his spell lists, is doing the same thing.

Some of the minis I bought on E-bay. Others I found at various on-line sites which sell individual minis.
