Late at night, on October 19th, Wal-Mart announced it was pulling animal toy sets from its shelves after discovering that they contained excessive levels of lead.

Wal-Mart said lead was not found in the surface coatings of the toys but in the base materials.

The retailer said it shared its results with the Consumer Products Safety Commission, but did not elaborate on how many units were affected by the recall.

The toys sets were described as "Farm Animals," "Dinosaurs," and "Jungle Animals."
