From the fleet news:

The seasonal Toon Tour service is not yet running, due to the ongoing COVID-19 pandemic. Despite this; open-top format Plaxton President bodied Volvo B7TLs 3997 (897 EYX) and 3998 (794 EYD) have been reinstated at Percy Main, and 3999 (574 CPT) at Riverside. As these vehicles are something of a novelty; they are expected to be used on frontline core commercial work on sunny days, with the aim of creating some happiness and fun during the current pandemic.


Never expected to see them in service this year at all.
