You've got a waterbuck swimming in your pool.
In my youth I asked my dad if we could get a pool.
NO! Ya' get a pool n' the first thing ya' know ya' got people coming over all the time uninvited to swim.
The above video proves he was right.
Although I think he was referring to people and not African waterbuck!
Tarangire Treetops Lodge had a different type guest swimming in their pool on the 21st of Match 21 2015.
The waterbuck eventually wanted to get out the pool and couldn't. So the helpful team of Tarangire Treetops Lodge came to the rescue.
