Here is the place where I saw this: http://feltron.com/ar11_04.html (in the right-bottom corner of the first page).
Crises is the plural of crisis. As they are listing countable items, they are using crises instead of crisis. This is a bit confusing since there is only one item on the list.
In essence she could make a list like so:
Crises involving ticks: 1
Crises involving monkeys: 0
Crises involving bees: 32
The crisis involving a tick is described as Olga found one attached to her and her mother removed it.
It is a use of hyperbole, as the finding of a tick attached to you would never be considered an actual crisis. But, rather, this person was highly distressed at having a small parasite attached to them.
