“Young ‘uns will eager­ly accept these col­lab­o­ra­tors’ tempt­ing invi­ta­tion to hop aboard this clever cumu­la­tive count­ing caper, which opens as a wild-haired girl in a small boat chimes, ‘I was a‑polin’ through the swamp, / only one, / only me, / when I came to the place filled with moss-cov­ered trees.’ There she encoun­ters a pos­sum ‘a‑swingin’, / a‑swayin’, / a‑dan­g­ly-wan­g­ly-playin.’ ’ He drops from the tree and, when asked the tit­u­lar ques­tion, con­fi­dent­ly responds, ‘If you got room for one … you got room for two.’ In turn, sev­en oth­er ani­mals invite them­selves on board, until the boat becomes mighty crowd­ed indeed: ‘Now we are nine, / not an inch more of space, / as we enter the waters of cold, dark Swamp Lake.’ The scale of the art and the type size sud­den­ly grow larg­er as a gator approach­es the boat. He does­n’t mind at all when he’s told there’s no room for him and pro­vides a deli­cious­ly droll denoue­ment. Booth’s com­i­cal pic­tures keep per­fect­ly in tune with Flem­ing’s riotous romp, as they intro­duce a cast of crit­ters with the inim­itable wide-eyed, seem­ing­ly elec­tro­cut­ed look that fans of his New York­er car­toons will imme­di­ate­ly rec­og­nize. Kids will be caught up in the zany visu­als and rol­lick­ing rhythm of this nat­ur­al read-aloud.” (Pub­lish­ers Week­ly)
