Pen Pals

From BoardGameGeek:

This is a game in Dr. Finn's Book of Solo Strategy and Word Games. It requires 2 dice, a pencil, and a game sheet (in the book). In this game, you enclose various animals using fence pieces, whose shapes are determined by the dice roll. You are trying to collect sets of animals in each enclosure and trying to make sure there is one water bucket in each. -description from the publisher
