Their favorite.
Their birthday.

A red monster has a clear visual identity, which makes it easy for a young child to recognize and connect with at the start of the visit. Ask the team how they would introduce the character, whether through a slow entrance, a call from the birthday child's name, or a moment where the monster asks the guests to help it find something. Each approach puts the child in charge in a different way. A shy child may want a gentle wave and a quiet hello, while a high-energy child might enjoy a dramatic arrival and a chance to shout back.

Discuss these ideas with the team and ask which greeting suits your child. You might also ask whether the monster can respond to the child's own name or favorite color, and how the performer handles a child who wants a hug versus one who prefers high fives from a distance.

An outdoor party can give a monster theme room to roam, with space for chasing bubbles, tug-of-war style games or a simple parade around the yard. Before you settle on an outdoor location, confirm with the venue whether outside entertainment is allowed and what the rules are for setting up a performance area. Ask the venue directly rather than assuming, because rules differ between parks, private yards and community spaces.

When you talk through the outdoor plan, ask the team which activities work well on grass or pavement, how they would adapt if the weather changed, and whether they would want a shaded spot for the costume and the child guests. Ask which activities suit your child and your guest list, so the monster's energy matches the group.

An indoor party gives you control over the room, the noise level and the seating, which can help a monster visit feel calm enough for toddlers and busy enough for older kids. A living room or a rented hall can both work, depending on how many guests you expect and how much open floor the team needs to move around. Measure the space and share the layout with the team before the day so they can plan a route in and out.

Ask how the monster would handle a crowded room, whether there is a quieter corner for a child who needs a break, and whether a single short activity such as a group dance or a sticker-decorating moment could be fitted into the booked hour alongside the main interaction. Activities are parts of the booked visit, not separate short sessions.

Young guests often do best when the visit has a clear rhythm: a welcome, a few playful moments, then a calm close. Ask the team how they structure the booked visit so the energy rises and falls, and where the birthday child can sit near the monster for photos or a special moment. Consider where the parents will sit and whether a child who becomes overwhelmed can step aside with an adult.

For arrival, ask how the performer will be brought to the venue, where they will change or wait, and who will guide them to the party area. Discuss these details with the team early so the handoff from arrival to the party feels smooth for the birthday child and guests.
