Tadpole

Help this wiggly little cell with a smooth oval head and a long somewhat undulating tail to reach the ovum without swimming into a deadly obstacle. Try to pick up all blue globes along the way but check that no other small fry enters the egg before you do. Your way is sometimes blocked by gray blocks that you have to remove to get to the egg. But be careful: if the blocks are red, you must not touch them in any case, otherwise you will die.
