At the end of the episode, a cactus patch in front of the camera moves across the screen. The cacti resemble Cattus' tail.

"The Cute Giant Cattus"
Cattus approaches the gang at their Gurunda campsite, eyeing BoBoiBoy's cup of water. Despite Gopal's protests to conserve water, BoBoiBoy offers his own drink to Cattus, causing the cat to warm up to him.

Personality
Being a feline, Cattus behaves much like a cat on Earth would act, albeit more aggressive. Cattus is shown to be very affectionate to people who help taking care of it, most notably BoBoiBoy and Papa Zola. In a short time, Cattus was able to bond with BoBoiBoy and grew angry when he had taken a hit for it. Cattus also has a strong bond with BellBot, who hangs around its neck.

When it wants something, it makes cute eyes to beg for it. When it's angry, the thorns on its tail will stand up. Other times, Cattus can be moody, picking and choosing it's fights and not always jumping in when it needs to.

After being long with Papa Zola, Cattus is shown to imitate his actions occasionally as shown in Episode 13.
