Energy at 600 units.
4 cells approximate cost 200 units of energy.

Score. Four cells and locate nearby lifeforms for consumption.

400 units of energy remaining.
Total cells 8.
Traits: Poison Resistance.
No lifeforms found, you did, however, find what appears to be a blood vessel to another area in whatever the hell organism you're in.

Go for it.

While your swimming err, pumping along the blood vessel, attack some of the blood cells (red only, no way we can bring the storm that are white blood cells down on us yet) to restore lost energy.

Do not do this, white blood cells PROTECT all other cells, not just other whiteys. No racism in physiology.

Hmm, is our disease cell small enough to enter inside of white blood cells?

If so, do so.

If not, just stay and eat.

if we can maintain contact with groups of cells throughout the host then prepare some new cells to send down the blood vessel for exploration or to start a new colony(or whatever the correct noun is). if not explore current surroundings and absorb weak or weaker cells on the way so we maintain energy. while exploring search for organisms, areas and objects of interest.

While we're around blood, perhaps we should be attacking other bacteria (I assume since we're cells we must be bacteria). That way the WBCs stay off our backs and we can more easily take down our prey, the cells of a multicellular organism usually being larger than single celled organisms.

Exert 50 energy to attack and absorb any poisonous bacteria in the area. After fulfilling that task use the energy from that to become poisonous.

There are no more bacteria or cells in the vicinity.
You send 4 cells down the bloodstream to search for more cells to absorb.
There seem to be more bacteria, as well as some kind of different, less aggressive cells.
400 units of energy remaining.
4 cells in starting area.
4 cells downstream.

Attack and eat any cells that we can safely take on.

You can either attack the benign cells or the bacteria, please specify which.

send a cell to see if it can identify one of the benign cells or see if it has any special traits, use the rest to hunt weaker bacteria.

The cell identifies the benign cells as part of the organism you're inhabiting.
The other 3 cells find and absorb 6 other cells, bringing total energy to 700.
4 Cells in starting area.
4 Cells downstream.
