Ostrich form doesn't spend movement points when it moves around. Is this the intended design? Movement points don't change, as the following log shows:

The Pass of Gol'Galath


In the moonlight a lizard roots around between rocks.

The Crossroads of Gol'Galath


A goblet of fine elven wine has been left here.
Alas, you cannot go that way.

A Mountain Trail
The trail here gently follows a downward grade towards the north. As
you progress, the air seems to grow warmer and less foul. To the east,
a grand forest can be seen stretching as far as your eyes will allow
you to view. To the west, the stone of the mountain rises up towards
the heavens. The trail follows the side of the mountain to the north,
while to the south far in the distance can be seen a crossroads.

A Mountain Trail
The looming stone wall of the mountain rises before you to the north.
To the east, a grand forest can be seen stretching as far as your eyes
will allow you to view. To the west, the mountain's stone rises up
towards the heavens. The trail here leads to the east, towards the
lush forest, while to the south the trail works its way up the mountain.
The air to the east seems noticeably less foul.

A Mountain Trail
The trail here gently follows a downward grade towards the east. As
you inhale, you sense a warmer breeze coming from the east where a
grand forest can be seen stretching as far as your eyes will allow you
to view. To the west, the trail continues to rise up into the mountain
peaks.


A key with a barrel-shaped top lies here.

Entrance to the Pass of Gol'Galath
The looming mountains of Gol'Galath reach into the sky to the west. A
worn and well-traveled path leads towards them, meandering its way out
of sight. To the east, a forest path leads deep into the woods of
Ar'atouldain. The white peaks to the west bespeak great cold, and
wisps of wind can be seen high up, kicking snow from the peaks of the
mountains. Such a spectacle looks as if the mountains are burning in a
white flame, with frigid smoke billowing towards the heavens.

On the mountains


(Glowing) A cheery campfire burns in a fire pit here.
An enormous, hulking troll stands here, glaring at his companions.
A huge troll grins menacingly in the direction of his companions.
A large hairy troll stands here grunting to his companions.

I won't rule out that the move cost might go up to 1 per room instead of 0 at some point upon further reflection, but ostrich is built to run.
