Headski is Redski and Belly is Blueski (Visual Imagery)
When imagining hunting animals in Russia, Gerald says he would catch a Russian Palooski, "whose headski is redski and belly is blueski." In this example of visual imagery, Gerald describes the starkly contrasting colors of the red-headed, blue-bellied birds.
Blistering Sands (Tactile Imagery)
When speculating about catching a scraggle-foot Mulligatawny from the Desert of Zind, Gerald describes the territory as having "blistering sands" so hot that the animal runs fast and steps high. In this example of tactile imagery, Seuss emphasizes the blister-causing heat of the sand the animal's feet touch.
