Magic School Bus; 5 oz.; PB Unread/Unmarked as new Gift Quality later scholastic printing. More details/pics upon request. Once again, Ms. Frizzle gets her class right in the "thick" of things--this time, they're right in the thick ooze of an underwater volcano's magma chamber! As Arnold and Carlos watch from a raft above, the Magic School Bus "erupts" with the magma and lava, and lands atop a brand-new island!
